If you are using the built in motion lighting app, there are multiple ways to override the motion sensors so their detections are ignored, whether that be auto on or auto off, up to you.
I personally have a virtual switch for every room that disables motion on/off in that room, then I expose that to Alexa and then all I say in that room is disable motion sensing and it does that.
But I also manipulate this switch with my goodnight routine for instance since the minimum brightness in the bedroom is still too bright, so saying goodnight disables the motion sensing in that room until I say good morning.
Another way I handle it, specifically in the family room with the TV, is through the power monitoring of my UPS (through NUT on a Rpi), which the TV is hooked up to. So when the power goes above a threshold, technically it polls the TV state, which is a Vizio TV which has its own hubitat driver, but you could get away with just if above power level X, disable motion sensing, if below power level Y, enable motion sensing.
But that app has room for a lot of overrides, one in particular I have been thinking of exploring is in the bedrooms and having a contact sensor on the door. So if the door is closed, motion sensing is disabled, and if the door is open, enabled.
