The user guide for focus modes (https://support.garmin.com/en-US/?faq=FJDLkz7bxF843FHYqTge4A&productID=1510465&searchQuery=focus%20mode&tab=topics) implies that it should be possible to turn off touch during the sleep and activity focus modes. But, there is no setting to turn off touch.
This is a problem in sleep mode. Last night my face touched the watch and started some kind of count down (I couldn't see what it was about; I just pressed Back and it quit).
I also think that touch should be turned off by default in Sleep focus.
