Disable touch screen on Apple Watch Ultra 2?

I've been a Garmin user for a while. The Garmin I has has a touch screen. However, I'm able to disable it during workouts. Why? Because I sweat! Now, with the Apple Watch Ultra 2, I haven't stopped sweating, but I can't disable the touch screen during a workout. It's very, very frustrating! I constantly get to the end of my 10K run or so, and I start getting segments in the Outdoor run because I'm sweating and it's getting on my coat (it's really cold now, below freezing) and the Ultra 2 is reading my sweat as a touch.

I'd love to be able to disable the touch during a workout!
