Fedora does use Sellinux, so I'm not sure whether vanilla Nix will work for you on Asahi Fedora remix. i've gone ahead and provided you with the files you'll need to get started. Just replace the 'Georgia' part in both files with the actual name of your user and home directory and you should be good to go.

Once you've installed Nix either through the official script or used Determinate Nix for their Sellinux support, give me a ping and I'll fill you on the next steps to get home-manager with flakes working.
