Nix iso unable to boot in UEFI mode (but other distros can)

for anyone else coming across this thread

I’ve been made aware of nixos/iso-image: Tear down GOP and rely on console for Linux boot · NixOS/nixpkgs@07fb2f4 · GitHub which apparently addresses this issue on the Steam Deck and possibly on other hardware. I haven’t yet tested it on my device, since the workaround of booting into Debian and kexec’ing worked for me.
