Was either of you bootloader unlocked prior to upgrading to 8.1??
If you were you should still be unlocked regardless of OEM unlock option.
My device shows orange state on 8.1 with TWRP installed but still boots fine and the OEM unlock option is greyed out for me too but that can be fixed with a simple setprop ro.oem.unlock=1 (I if I remember correctly )

*Unlocking bootloader will remove all your data!*

I'm using Windows 7, and that's the steps i did. (it should be simmilar for other systems too)

Getting code:

Code will look simmilar to this: DB1ED223C5537BA756FB0671E425D650

Method 1 (no root):
Go to
https://passwordsgenerator.net/md5-hash-generator/ copy paste serial number and click generate. Then you should see code in "MD5 Hash of your string". You can also go to simmilar md5 hash generator sites, but this site automatically converts small letters to big letters.

Method 2 (root):
Okay, this is new method that is much easier and you don't need to send IMEI and wait for @the_laser to give you code. Go to terminal emulator, type su and execute it. Then type this and execute it:

Unlocking bootloader:

Download platform-tools which activates adb and fastboot commands (first you need Nokia 3 driver installed if you didn't)

Nokia 3 driver: http://www.devfiles.co/download/3iK0k7Sv/Nokia_3_USB_Drivers.zip

platform-tools Windows: http://www.devfiles.co/download/KtLsN6fX/platform-tools-latest-windows.zip

platform-tools Mac: http://www.devfiles.co/download/OkrfluP0/platform-tools-latest-darwin.zip

platform-tools Linux: http://www.devfiles.co/download/vk5DudZX/platform-tools-latest-linux.zip

Enable usb debugging in Developer options before running adb. To get Developer options, go to settings, about phone and press build number 7 times. Also enable OEM unlock.

Now Connect phone to computer via usb and enable usb file transfer, run cmd as administrator, then type this command which runs adb:

chdir C:/Users/John/Desktop/platform-tools (this is just a example, you need to type your own location of platform-tools)

then type this command to check is your device connected to adb, it will show serial number of your device, if it hangs at waiting device, then you need to reinstall drivers (if you're doing this first time, then it will ask to allow usb debugging on your computer, just tick always allow from this computer and click OK)

adb devices

then type this command to reboot to recovery (you can boot to recovery by holding power on + volume up (only with usb connected) if this command doesn't works)

adb reboot recovery

when booted to recovery, choose reboot to bootloader option with volume sliders (this will boot to fastboot)

when booted to fastboot, it will show text 'FASTBOOT MODE' in down-left corner
now type this command to check is your device connected properly to fastboot.

fastboot devices

if it show characters like 0123456789ABCDEF or simmilar then it is connected properly, if it hangs on waiting device, then you need to reinstall drivers like mentioned above.

Android Nougat:

Now type these commands to unlock bootloader

fastboot.exe -i 0x2e04 oem key (type your key after oem key)

fastboot.exe -i 0x2e04 oem unlock
then press volume up, when asked

Android Oreo:

Now type these commands to unlock bootloader

fastboot oem dm-verity <your_unlock_key>

fastboot flash lk NE1-0-215H.lk.bin

fastboot reboot-bootloader

Proceed your unlock procedure.

If you have problem on flashing the lk partition, you can use MTK Smart Phone Flash Tool to flash lk partition manually.
After lk partition flashed, you may encounter "Red State" when booting the phone. Ignore that and boot your phone to Fastboot mode directly with OST LA.

That is it, i tried to explain for you to understand everything i did to unlock bootloader.

Credits:
@the_laser for codes, some additional steps and corrections. Also thanks for new method. @redweaver for new method. @Hikari_kalyx for Android Oreo method.

You didn't mentioned where do we get NE1-0-215H.lk.bin.

You didn't mentioned where do we get NE1-0-215H.lk.bin.

you can get it from NE1-0-215H nb0 file. I think that i have it, i can upload it later.

Bricked is a strong word.
Where did you get to ?
Did it start the flash?
Need some detail to help mate

EDIT:
I recall having something similar once so I loaded the recovery.img and boot.img (firmware stock 7.0 at the time) hit download. While the phone was looping SPFlashTool will catch it and stop the loop then flash them.

Which model is your's TA-10XX

Did you manage to do the bootloader unlock procedure then??
If you did it doesn't matter your bootloader will remain unlocked.

No. I have OEM unlocking option greyed out. I managed to downgrade to 7.1 with SP tool but the phone wont start until you update to latest version from the Android setup....

Maybe you should try give some detail.
You have not said what your variant is TA-10XX since your in the US that maybe important.
What version of 7.1 did you flash and where did you get.
What parts of the 7.1 got flashed
I can't read your mind and every situation is different so until I have a clear picture of where you are at I cannot advise you so for now I have no idea's as I have never had these issues you describe. .

Ok. So i'm not currently in US . The phone is an european model TA-1032 DS ( bought from Romania sim Free) . I flashed full firmware Nokia3_MT6737M_Heart_FIH_7.1.1 with SP Flash tool. An when i want to Setup the device..it tells me that i need to connect to Wireless to continue.

OK now it makes sense.
That is frp at work google needs you to connect to wifi or data to check your account the frp stores your unique id and forces you to sign in with those details.
It's incase someone stole the phone and did a factory reset it still needs your account to activate it.
Google "frp reset" to get rid of it if you want and that may allow you to bypass the forced update.
If your good with spflashtool and can read your scatter values (start and length of frp) you can wipe the frp by the format option but make sure your 110% happy or you may well brick it.

@RazOne i also hate Oreo, if you want to stop update downloading automatically, you can disable that in Developer options.

I have managed to bypass the setup. All fine now. Nougat is so smooth compared to ****ty Oreo. I think they do these updates to make you change the device.

I can not unlock the bootloader (oem unlock is gray, and fastboot devices command no list my device), and I can not force the flash to nougat for that.

What is the quick route to suicide? I hate not being able to root my phone and install a simple audio mod

roll back to android 7.1.1, 7.0 that's the only way.
And audio mods will not help this device, it has a crappy bult in DAC, my old Nokia phone from 2012 has better audio quality.
