No VRR in neither 545 nor 550 drivers on Pascal Cards on Wayland (GTX 1060)

Since the launch of the 545 driver, one of the additions was VRR support under Wayland, but I’ve been out of luck since because I don’t see such option in my KDE Plasma desktop.

However, I do see VRR on the X11 session, but I haven’t used X11 in a year and would prefer to stay on Wayland.

Is this a bug, or are Pascal cards VRR unsupported on Wayland? Will this change in the future?
