Overclocking monitor on KDE wayland

Hello, as title says i’m trying to overclock monitor refresh rate on KDE 6 wayland. Every guide on internet tells to add kernel parameter so i did “video=eDP-1:1920x1080@90” but it didnt change anything. On x11 we have xrandr soft that can do this but how about wayland? I also found kwinoutputconfig.json file and changed refresh rate but again it did nothing. Another try was with kscreen.doctor but it says “Output mode 1920x1080@90 not found.”. So how to add new mode?
