VRR support for MPV is disabled by default in /usr/share/drirc.d/00-mesa-defaults.conf. I am not sure why, because it works for me if enabled. Just fullscreen MPV and it will change the display refresh rate. This requires VRR enabled in both Xorg and your monitor's settings. I have not tried this with Wayland.
