I assume your television is connected to a Winegard wall plate “power injector “ selector? (On the phone app, user profiles are not shown.)
If so, you can easily unscrew the wall plate and move the cable coax to the antenna connection. With ANT selected, whatever is connected to the cable port will then be treated as an antenna, including being supplied with the power feed.
Maybe label your changes so you don’t forget? (Or for the benefit of the next owner)
