The option to reassign touch sensitive areas can be found under Options / Reader / Gestures. At least for the premium version of Mantano.
There you can specify what effect, if any, swipe left / right / up / down or single tap left / right / top / bottom / center should have.
I mapped both single tap left / right to next page, and kept swipe left / right mapped to previous / next page.
