Disabling home-manager

Hi! When I first discovered this repo I was very excited to be able to carry some Garuda defaults to my new NixOS installation, but I'm having a lot of trouble trying to disable the home-manager stuff that gets added (I don't want anything to touch my dotfiles but me).

I thought I found a way how with systemd.services.home-manager-cdfa.enable = false;, but packages from internal/modules/base/home-manager/dotfiles.nix are still being installed. I found out about this while trying to figure out why kinfocenter-5.27.11 was installed despite me being on plasma 6. I'm still not sure why, but in an attempt at debugging I did

  nixpkgs.overlays = [
    (final: prev: {
      libsForQt5 = throw "hit";
    })
  ];

which pointed me to home-manager through the following log

I hoped setting garuda.excludes.home-manager-modules.excludeAll = true; would fix it, but this option does not exist because gCreateExclusionOption is never called for home-manager-modules.

I would love to have an option like garuda.home-manager.enable to disable all the home-manager stuff.

For reference, my garuda module config:

  garuda = {
    performance-tweaks = {
      enable = true;
    };
    garuda-nix-manager = true;
  };
