Just put Asahi on there, or any linux you like. I'm sure the support will be there soon if it's not already.
That's not a thing. Apple silicon doesn't use EFI so you need a completely custom ROM to satisfy the boot process, hence Asahi. And Asahi doesn't support M4 and likely won't for a while.
ARM64 support for GUI apps (via flatpak in the Fedora Asahi Remix) is also pretty poor, though your standard fair of CLI apps are present.
M4 support will come.
