Oddly, I haven't seen that discussed anywhere.
The "Liquid Retina" displays support up to 120 Hz and you can set different refresh rates in the settings. Also, we know that macOS now supports adaptive sync displays.
So a natural conclusion would be that the screen refresh rates adapts to whatever happens on screen (including games) on these laptops. But I haven't seen that reported anywhere.
Apple has discussed VRR in the context of ProMotion (WWDC sessions), but only for iPads. They also discuss macOS, but only in the context of adaptive sync external displays, not ProMotion displays. Adaptive sync and ProMotion are not synonymous.
So the fact that Monterey supports adaptive sync for external displays does not necessarily mean that MBP ProMotion displays also do.
Unfortunately, Apple doesn't provide us with any tool to report the screen refresh rate on these laptops. The Metal HUD does not.
So how can we tell if the screen refresh rates adapts to a game frame rate?
Note that absence of screen tearing with V-Sync off is not a proof of VRR. It could just mean that Metal enforces V-Sync (which I think it does on iOS).
Intermediate frame rates without screen tearing are not a proof of VRR either. All games and the Metal HUD report intermediate frame rates between 30 fps and 60 fps on my 5k iMac, regardless of V-Sync. And that machine definitely doesn't support VRR.
