Use custom nixpkgs version while flake?

[daniilrozanov]

I'm using this package as a flake:

...
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";

    nixpkgs-stable.url = "github:nixos/nixpkgs/nixos-25.11";

    apple-silicon.url = "github:nix-community/nixos-apple-silicon";
    
    home-manager = {
      url = "github:nix-community/home-manager/release-25.11";
      inputs.nixpkgs.follows = "nixpkgs";
    };
}
...

Is there a way to override apple-silicon's nixpkgs version to use my current nixpkgs? Like home-manager does?

PS. Is it even OK to use nixos-apple-silicon as a flake? Now that I've done that, everything works, but the Asahi-Linux kernel gets recompiled quite often while I'm updating the system, and that's annoying

You can override the inputs of any flake using the same syntax home-manager uses:

apple-silicon = {
  url = "github:nix-community/nixos-apple-silicon";
  inputs.nixpkgs.follows = "nixpkgs";
};
