They support nouveau. Wayland doesn't support EGS, no matter what DE you stick in front, so nv drivers are out.
(Nvidia cards have two drivers on Linux, nouveau, the open-source, slow, and incompatible-with-Quadro ones, and NV, the binary blob shipped by Nvidia that people take religious exception to.)
Gnome supports Wayland over EGS just not by default. I tried it out a few months ago and while it "works" it was somewhat buggy and I just went back to X.
What's EGS in this context? I'll take it it's not the Epic Game Store, and searching for Wayland EGS only lands on this HN comment.
EGLStreams, one graphics API. The alternative is graphics buffer manager with kernel mode settings.
Gnome and KDE on Wayland support both EGS and GBM, and they have for a while, so the nvidia binary driver "just works" with either of them.
