Replacing X11 with Wayland on KDE Plasma 6

Currently, my kde plasma has xorg and wayland but I just want to use wayland. As I mostly just use vscodium and browser most of the time. I tried commenting out the services.xserver.enable = true; as per the comment it generated by default that if I do not use x11 i should delete/ comment this line. But, that does not work and just keeps me inside the tty. Can anyone give a the guide to remove it fully? Oh, can I use LightDM instead of SDDM? Not a fan of this display manager. I added my configuration.nix below if needed. Thanks!
