I just put back the DTPG SSDT and it didn't make any difference, I still don't see any thunderbolt devices and none of the monitor's built-in functions work. Maybe it comes down to which version of the monitor you have?
Wow, I tried the same thing but didn't have any luck. Are you using a Titan Ridge 1.0 or 2.0 card? And what version of the LG 5k are you using? I'm on the initial release before they updated the power delivery spec etc.

It looks like Big Sur breaks LG UltraFine 5k support. I had it working well with my Z390 Aorus Pro and Titan Ridge 1.0 card with Elias23 firmware but on Big Sur the monitor doesn't turn on when I boot or restart. Has anyone else gotten their setup to work with Big Sur?

@gandem I tried the modified NVM50 firmware you posted and my 5K UltraFine still doesn't show the BIOS POST or the Opencore Bootloader, but once booted into MacOS the monitor wakes up. The monitor shows the BIOS etc. on reboots.
Thanks for confirming with your experiences! Is the patched NVM 50 firmware floating around in this thread? If so would you be able to link me to it? I did some googling but wasn't able to find it. Also have you noticed any differences between patched 23 vs. patched 50?
I want to check in with my experiences with Titan Ridge cards and my 5k UltraFine display.
