Yeah:

    xserver = {
      enable = true;
      xkb.layout = "us";
      videoDrivers = [
        "amdgpu"
        "radeonsi"
      ];
      displayManager.startx = {
        enable = true;
      };
      desktopManager = {
        xterm.enable = false;
      };
      windowManager.bspwm.enable = true;
    };
