In our 2019 F150, there’s a plug block with three plugs under the dash. The plug on the right side of the block handles the towing connection at the rear bumper. Unplugging the plug on the right disables the towing connection...but also disables the auto stop/start. Just leave it unplugged until you need to tow. That being said...I don’t do that. I just lift my foot off the brake and the truck restarts.
I worry more about the wear and tear with the repeated use of the starter.

That is what I did. I don’t care how much they engineer it, it is not good for you engine to stop and re-start every time your vehicle stops.
This was done to help the vehicles meet the CAFE standards.
