Building on raspberrypi4 failed: Module sun4i-drm not found

[Just-Ch33s3]

i gave nixos-generators a try with:

nix-shell -p nixos-generators
and
(sudo) nixos-generate -f sd-aarch64 -c /etc/nixos/configuration.nix -o ~/nixos-sd-card.img

it resulted in the following error, would anyone be so kind an lead me to the correct path to solve the sun4i-drm module not beeing found ? Thanks in advance!

solved it by adding a layer to my config;
....
let
...

overlay = final: super: {
makeModulesClosure = x:
super.makeModulesClosure (x // { allowMissing = true; });
};

in {
...

add overlay

nixpkgs.overlays = [ overlay ];
}
