It’s bad enough to just see the Flarm collision alert screen with the red 12 o’clock the whole time on tow, but having the constant beeping is just too much to tolerate.

What about turning the volume down until you're off tow? If you hook up an external speaker, you could use a SPST switch?

I agree that you don't want to block alerts on the tow plane and you don't want the tow plane to turn off ADS-B out during tow.
