Config for GA402X broken?

[codingCoffee]

I'm trying to configure my Asus Zephyrus G14 GA402X laptop with viz this

Here is my flake.nix

{
  description = "my flake!";

  inputs = {
    nixpkgs = {
      url = "github:NixOS/nixpkgs/nixos-23.11";
    };

    nixos-hardware = {
      url = "github:NixOS/nixos-hardware/master";
    };
  };

  outputs = { self, nixpkgs, ... }@inputs:
    let
      lib = nixpkgs.lib;
    in
    {
      nixosConfigurations = {
        zephyrus = lib.nixosSystem {
          system = "x86_64-linux";
          specialArgs = {inherit inputs;};
          modules = [
            ./configuration.nix
            inputs.nixos-hardware.nixosModules.asus-zephyrus-ga402x
          ];
        };
      };
    };
}

Ref: picked up the config from

nixos-hardware/flake.nix

Line 25 in ad2fd7b

asus-zephyrus-ga402x = import ./asus/zephyrus/ga402x;

This is the error I'm facing

$ sudo nixos-rebuild switch --flake .
error:
       … while calling the 'seq' builtin

       error: The option `amdgpu' does not exist. Definition values:

I'm relatively new to nix, so is this some relative import problem? Or is my method of using nixos-hardware repo incorrect?

[codingCoffee]

Dug a little deeper, realized the problem was in my config. I need to explicitly mention which GPU config I'd like to use.

nixos-hardware/asus/zephyrus/ga402x/default.nix

Line 4 in ad2fd7b

# nixos-hardware.nixosModules.asus-zephyrus-ga402x.amdgpu

nixos-hardware/asus/zephyrus/ga402x/default.nix

Line 9 in ad2fd7b

# nixos-hardware.nixosModules.asus-zephyrus-ga402x.nvidia

So, effectively my config became

{
  description = "my flake!";

  inputs = {
    nixpkgs = {
      url = "github:NixOS/nixpkgs/nixos-23.11";
    };

    nixos-hardware = {
      url = "github:NixOS/nixos-hardware/master";
    };
  };

  outputs = { self, nixpkgs, ... }@inputs:
    let
      lib = nixpkgs.lib;
    in
    {
      nixosConfigurations = {
        zephyrus = lib.nixosSystem {
          system = "x86_64-linux";
          specialArgs = {inherit inputs;};
          modules = [
            ./configuration.nix
            inputs.nixos-hardware.nixosModules.asus-zephyrus-ga402x.nvidia
          ];
        };
      };
    };
}

The issue can be closed. But should this be fixed in flake.nix file by splitting it into 2 lines to make it easier for a newcomer?

nixos-hardware/flake.nix

Line 24 in ad2fd7b

asus-zephyrus-ga402 = import ./asus/zephyrus/ga402;
