After looking into the problem with the NFC not working, I have found a Workaround!
This allows you to have fully working NFC functionality on any ROM including DotOS, Project Lighthouse, Havoc OS and LineageOS. It is a permanent fix as long as you don't go back to stock, If you do go back to stock you have to repeat the steps again.

1. Download LineageOS 15.1, The ROM of your choice and any extras.
2. Reboot to Recovery
3. Format Data
4. Reboot to Recovery
5. Wipe Dalvik, System, Data, Internal and Cache
6. Flash Lineage 15.1
7. Boot and setup LineageOS
8. Check NFC is Working
9. Reboot Recovery
10. Format Data
11. Reboot to Recovery
12. Wipe Dalvik, System, Data, Internal and Cache
13. Flash the ROM you want and any extras.
14. Boot and Setup
15. You Should have working NFC!

LineageOS 15.1 can be found here: https://xdaforums.com/t/rom-h830-h850-rs988-unofficial-lineageos-15-1-for-g5.3806842/

I am not sure why this works but @etmatrix believes that flashing from the Stock ROM (8.0.0) to anything higher without using a ROM of the same android version first locks the NFC functionality.
LineageOS 15.1 runs Android version 8 which is why we are using it.

My theory is little different. LG G5 has a hardware lock when the device is encrypted. If you remove the encryption with format, the hardware lock is not removed, is still configured.
I think but I can't verify, because requite many time to restore and try, which the hardware lock locks also the download firmware for security reason.
When I installed for the first time LOS 17.1 in logcat I have an error while nfc service try to download the firmware in chip.
I tried the long procedure start from android 7, install LOS 15, 16 and 17 and I resolved, but in this procedure, when I restored android 7, I removed the hardware lock, for this I think it is the hardware lock to broke NFC in LOS.
A day when I will have spare time and a new device, I'll try.

IR is working? On LOS 17.1 and 18.1 after the first command the chip stuck in slow blinking.
I opened an issue

Just tested and it's not working.

How about Location GPS Satellites Only Fix on this ROM? Havoc and LOS18.1 are missing out on this.

I don't know if this is also your case. When my device was in stock rom, I discovered this bad issue after some months. I never found a permanent fix, for me in LOS 18.1 GPS is working.

DotOS uses the Lineage Device Tree so it will share the same issues unfortunately.

Do you know what ROM it last worked on? Would be helpful to try and get it fixed

LOS 17.1 Summer 2020 builds
I'm aware of HW issues on g5.
I'm sure mine is fine, since I've opened and fixed it by myself and satellite were working fine on those builds.
Also pattern of how satellites are showing in view is weird Some time no satellites in view at all and then one shows up with ≈25ish signal in GPS Test app.

Thanks, I will try and take a look into that. It's difficult for me to test as I have just found out my GPS doesn't work at all on stock ROM. It was finding 0 satellites but cleaned the pins inside and straightened them up a bit and it's now finding 35 but it's not connecting to them.

Maybe the better solution is this but I've never tried it.

My gps is now working fine on all ROMs including DotOS and LOS 18.1
I have attatched some images to show that its using GPS Satellite only as well.
Maybe its a hardware issue?

Thank you. That's valuable info for me. I'm on havoc ATM, might consider moving to DOT even though I'm not a fond of it's ui.
How about Bluetooth media buttons?
On LOS and havoc I can press pause while music is at play, but I can't unpause it with the same button without unlocking phone first.

No Problem. I have just tested this by connecting my "Xiaomi Air 2s" Bluetooth earphones to the phone and I can play and pause music while the phone is locked from the earphones and the lockscreen.
