Official unlock is possible from September Security patch. Unofficial is possible till July one. On August one you can do nothing. There are two ways for you:
1) Stay on June, unlock unofficially and than update till later patches.
2) Update till at least September and unlock officially.
The difference would be that for unofficial you have to pay couple of bucks, but you do not inform HMD that you unlocked bootloader. So if you need to use your warranty, you can always relock and HMD won't know that you did something with bootloader. With official way unfortunate you will inform them and process of using your warranty is totally up to them. In general applying for official unlock you agree to skip you warranty. That is official statement from hmd. Of course of something worth your phone goes wrong, you can always try, but all in all they can say no.
I'm stuck with June Update :/

Thank you for getting in touch with Nokia Mobile Care. It's important for us to have you as our customer.
I understand how frustrating is when we do not get the answer we want to have. please note that here we are just a remote customer care and there nothing else we can do to you, we will always say the same thing, because this is what we are advised to do. Whit doesn't mean that we are not giving you a good and satisfactory support.
Every Nokia phone, after manufactured receives a series number and it is delivered to a specific market that it was manufactured for, each market has different specification, pieces, system, laws, government technology statement, etc. with means that even you you get two Nokia 8 from the same store at the same day, there is a possibility that that two devices can be manufactured with different series number.
This is the reason why Nokia says that it will allow to certain phones only, it means that none all phones, even if they are all Nokia 8 will be allowed to have the bootloader unlocked. If you are receiving the message "device not supported" that means that your device is not supported to have the bootloader unlocked.
Thank you so much for your understanding on the situation here. Now understanding that I have already gave all the information that I have in order to explain you why we do not have the information about the Bootloader unlocking code, I will then be closing this ticket.
I hope that the above information is useful.

Again shows how uninformed they are. While that generic statement is correct, for example the phones sold in China aren't probably eligible for unlocking. The remainder is a uninformed reply. The not supported is a problem due to the latest update for which the server is not modified. So, none of the Nokia 8 on Pie will be supported, irrespective of the model or the market where it was sold.
I was so upset about the silly response. Luckily i found a workaround posted a few posts above. Downgraded manually to 8.1 november security patch then used the app, it gave me the unlock code without error and i was finally able to unlock the bootloader. I then sideloaded the december pie update and then flashed a december pre-patched boot img to finally get root on this phone. Now im busy restoring backups and all. If it wasnt for the community i'd have given up and sold this phoneAgain shows how uninformed they are.

Thanks, I finally got it to work with Win10, not sure what did the trick though as I tried a ton of things. Oh andAll of course once you're in fastboot you can't get ADB to work, it's only fastboot, had forgotten about that so I wasted a bit of time with that.
Up and running now but I'm a bit concerned about future updates as I can't do the October update when I'm booted into Slot A, even with Magisk removed and with stock_boot_nb01_488_sp04_sep.img - that should work right ? Or it sees it's not my original boot image ?
The best way is probably to wait until Pie gets released. If it works on Pie, everything is good. If not, take your phone to a service point and ask them to downgrade it to Oreo,
either with a made up excuse like you have a critical work app that only runs on oreo, or just with the real reason, it's supposed to be official after all.
This would bring you back to May or June IIRC, so you could just update to September and unlock officially, or use the unofficial method if you got a key for it.
