Valve also had already spent considerable resources in making proton work well with AMD. even if an appropriate SOC was to be available from NVIDIA, it is possible that Valve would have chosen AMD.

Mind, proton does work well with NVIDIA, but my understanding is that AMD gets the most testing.

NVIDIA doesn’t have the license to make x86 chips with the modern patented features so they’d need to either have a dedicated GPU with an AMD/Intel CPU or develop, or invest resources into an existing, ARM emulation layer

Or sell a small die for AMD/Intel to package, ala Vega-M.

Or contract Centaur before they went defunct, maybe?

Both these things would be quite out-of-character for Nvidia.
