Struggling to overclock monitor

How should I do this?
Wayland, will not go to X11. AMD gpu as well.
I can’t seem to find a way to force a mode to be changed or created. I know on windows I can easily do it through AMD drivers but it seems much more difficult on Linux for some reason?
For the record, my monitor natively supports 1920x1080@60 but it CAN do up to 1920x1080@75, it’s just not a listed mode.
