I’ve been wondering if there was support in the bios for using a gpu hooked up via an M.2 to PCIe adapter instead of the cpu’s integrated graphics. Can this be done? Has anyone tried to do this before?
I don’t believe that requires BIOS support, PCIe is surprisingly adaptable! As long as you have another boot drive (from USB) you’ll be able to do this!
In fact I think if I remember correctly someone who set up a home server (out of Framework mainboards) did exactly this!
Why bother? Are you trying to avoid Thunderbolt overhead specifically or are you unaware you can attach a GPU through the Thunderbolt ports?

Thunderbolt adapters tend to be pricier and more finicky than a direct PCIe connection - after all, PCIe in Thunderbolt is tunneled, not native, and Thunderbolt doesn’t always work wonderfully either.

I think Thunderbolt is still pretty viable, I found this video on YouTube yesterday about using GPU
