Me again. The guy with the NIC problem from before.
I installed the Rx590 and it shows up in lspci as an RTX 2070. I was hoping it was just Proxmox not having drivers or something, but when I pass it into the Hackintosh it's meant for, it shows as NVIDIA there too:
Now I did get the Rx590 off eBay, but I'm it was listed as and looks like this: https://www.powercolor.com/product?id=1551768831
So I think it is actually a Rx590.
This is lspci. 01:00.0 is a RTX 3060. 03:00.0 is the Rx590.

It seems unlikely that with this lspci output you actually have a Radeon.
Any sticker on the board that say it's a Radeon? Maybe the seller "accidentally" swapped the heatsinks with a different card when cleaning that (but GPU heatsinks aren't universal like this IMHO)
Try on a different computer as a main GPU
