This is most curious

I have question about overriding nix files. I want to override the sdImage.populateFirmwareCommands from the imported <nixpkgs/nixos/modules/installer/sd-card/sd-image-aarch64.nix>. What would be the best way to do this?

For now I have something like this:

in
{
  imports = [
    sd-image

  nixpkgs.config.packageOverrides = pkgs: {
      sdImage = sd-image.sdImage.override {
        populateFirmwareCommands = "overrideCommands"
     }
  }

For now I have something like this, it builds but the command is not overridden.

let
    sd-image = import <nixpkgs/nixos/modules/installer/sd-card/sd-image-aarch64.nix> { inherit pkgs config lib; };
in
{
  imports = [
    sd-image

      sdImage = sd-image.sdImage.override {
        populateFirmwareCommands = "overrideCommands"
     }
  }
