I'm afraid that ship has sailed. Tesla changed the expectation of buyers that touchscreens are more 'luxurious' so the market follows. I prefer physical knobs too, but don't blame car makers for following market trends.
Fortunately, some car companies are seeing the light of physical control. For example, Honda had mainly touch-only controls on the last generation Accord, but then added a bunch of physical buttons back for the 2018 model.
