A few years ago, I bought a product by Durasafe that replaces your electronics knob with a keyed lock. The keyed sleeve fits over the other piece and doesn’t allow access to the secured screw. This relatively inexpensive tool may be all the security you need.
Those that are on a tight budget might want to consider an alternative. I had a tight fit between my console and windshield and the large manufactures electronics knob were close enough to the windshield I decided to look for another option. I simply replaced the plastic supplied knob with a bolt of the same length. Implement a large fender washer and a rubber washer and you are good to go.
Here are some thoughts.
