@henryrym - I'm going to be busy for a few days. Fortunately, there are others contributing to this thread who are very capable and able to help you.
@henryrym - I had a free minute and can give some feedback. I don't want to do this for you, because I'd be doing you a disservice (and you want to learn and be able to maintain your hack). You should review these three threads for UHD 630 Framebuffer patching:
Here are a few hints:

Here are a few hints:
- The connector types in the EFI I posted are specific to my system (DigitalDVI). Review all Known Issues (including Catalina Issues) to learn about this and other potential differences between your system and mine.
- Your DP ports are identifed by type 0x0400, reverse byte order <00 04 00 00> (where my DigitalDVI connections are type 0x004, reverse byte order <04 00 00 00>). Learn about reverse byte order in my "My framebuffer patching experience" post linked above.
- Your VGA port is identified by connector-type 0x0010, reverse byte order <10 00 00 00>
- @rafale77 's Graphics Device Properties in his EFI here are closer to yours than are mine in my posted EFI. Look at his config.plist to see how he patched for 3 DP ports. You may find that you need to change your AAPL,ig-platform-id to 0x3E9B0007 (reverse byte order <07009B3E>) for working sound over DP.
