I did this for my BIOS I am also on the latest for my motherboard but I cannot get hot swap enabled for some reason. Also I tried to use a elgato thunderbolt 3 dock and everything but the thunderbolt port mounts. I hope there is a possible solution to this problem or maybe using a different card for thunderbolt?

Thunderbolt 4 on non-Apple computers is not as flawless as Thunderbolt 3 due to the lack of the drivers.
 
Hi, I have Thunderbolt working without HotPlug. I have an Asus Thunderboltex 4 card on a B550-E ASUS motherboard with Opencore 1.0.3. I followed the guide step by step, but I feel that my ACPI path is a little confusing. I attached a screenshot of my iOReg where I had to search for my Apollo sound card there because nothing related to Thunderbolt is showing up.

I would appreciate it if someone could help me.

PR:
  1. Thunderbolt Maple Ridge
  2. Thunderboltex 4 Asus AIC
  3. Asus Rog Strix B550 E
  4. Ryzen 7 5800x
  5. Opencore 1.0.3 - MacOs 15.3.2

As per your IOReg, the address seems to be PCI0.PT02.PT20.X163. You'll have to adjust the path the SSDT.
