Is there a way to ensure that Virtual Desktop uses ASW below a certain FPS?

Basically, my issue is playing DCS with a Quest 3. If the frames drop slightly below the amount I set in VD (in this case 72Hz), the head tracking gets really choppy. If it drops low enough, ASW will turn on, and I get 36fps, but the head tracking is smooth. The problem is when the fps is bouncing around, say 65-70fps, ASW won't turn on. I'd rather have a lower frame rate, but smooth head tracking in that case. Currently I have ASW set to auto in VD...is there someway to adjust the threshold where it comes on?

UPDATE: I only just learned that you can access the VD menu while still in game, so I guess I could just turn SSW on/off manually if I want to. Would be nice to have a hot key for it, though.
