I have a pic here. I went into my BIOS of my ASROCK Gaming Phantom and I can't find any option involving PCI subsystem or 4gb encoding. Any idea what specific option I'm looking for here? I have a Ryzen 5900x paired with this new 9060xt. Thank you for any help.

Thank you because I was having a hard time finding it but I was able to use these guides to at least have an idea of what the folder it was in was named. then when I found it, it was greyed out. I had to disable CSM support, but that option wasn't showing up anywhere, so I asked gemini and it said it's an option with fast boot. I clicked off fast boot to see what would happen, and the CSM folder magically appeared when I turned it off. Then I turned off CSM, then I enabled fast boot again. Then the CSM option disappeared again but 4g decoding and resizable bar became clickable, so I assume CSM is still off. So we'll see if I blue screen while gaming and photo editing today.
