what part number headlights did you go with? Where did you source them?
I’m very interested in doing this also, in the US.

I am still playing with the GAP tool. The PIVI reset has been done number of times 
, No luck yet. Check this out it might be helpful as I have seen your post where premium/ matrix was discussed.

These are mine LR144293 and LR144290. I got them from Allegro, Poland
I suspect that I have to upgrade my BCM in order to let the ADB appear or to
code the lights to the VIN.

I did it finally. I will post the complete list that has to be modified soon. The Matrix lights are a must have upgrade. Special thanks for @Patrick and the GAP team.

Doesn't work on my 2020 either. Everything else that I've tried has worked though...Dynamic, ACC, and FOB tailgate opening. I did get Park Assist to show up, but I get nothing once I'm in the screen/mode; just a steering wheel icon.

Here is the list of changes that I had done to enable Matrix Headlights in my car. Everything is working as expected. In the menu - exterior lights - HD Adaptive Driving Beam toggle has appeared. Functioning as expected. I suspect not all of them are needed and I will update the list once it is verified.
