I can look into adding support for that. At the moment, you will need to go to Settings->Touch & Pedal Settings->Touch Actions, and just disable tapping to turn pages. Then while you are in performance mode, only a swipe or a pedal should be able to turn the page. I can double check this tomorrow but I believe it should work. A more convenient toggle for this (such as long pressing the performance mode icon) should be pretty easy to implement.
