So dynamic memory clock switching will be disabled whenever VRR is enabled?

Note that there is ongoing discussion about how Wayland compositors could usefully keep VRR enabled all the time, as opposed to only while there's a fullscreen application like a game. So "VRR is enabled" likely won't be equivalent to "game is running" in the long term.
