Got to be a replace unless you can live with it. I have the Tesla branded Pet Liner for the back seats. It does a good job of protecting the seats and comes with door panels. I have to say I gave up on the door panels because they were constantly falling off. Each time the window returned from the dropped position when the door closed they got looser and would dislodge in short order. I'm not sure they would deter a determined chewer but would offer some protection if you were more successful than I was keeping them in place.
