You can get chew stop for rabbits/rodents from pets at home. I got my buns different natural chew toys, cardboard boxes for distraction therapy!! Do you shut them away at night or when you are not in?
I taught my buns the word 'no' you reinforce it with a firm bang on the ground with your hand which means danger in bunny language. Mine were shut away when unsupervised in their own large utility room which had no wallpaper or carpet!
