Any way to get to get all `options`?

[ging-dev]

This doen't working, it would be helpful for nixd (https://github.com/nix-community/nixd/blob/main/nixd/docs/configuration.md)

(builtins.getFlake (toString ./.)).systemConfigs.default.options

Updated:

(let self = builtins.getFlake (toString ./.); pkgs = self.inputs.nixpkgs.legacyPackages.${builtins.currentSystem}; lib = pkgs.lib; in lib.evalModules { modules = [ self.inputs.system-manager.nixosModules.default { config.nixpkgs.hostPlatform = "x86_64-linux"; } ]; specialArgs = { inherit pkgs lib; nixosModulesPath = "${pkgs.path}/nixos/modules"; utils = import "${pkgs.path}/nixos/lib/utils.nix" { inherit lib pkgs; config = { }; }; }; }).options
