[Q] How do I disable tap to unlock topic

I have the Verizon LG G2 and love it. The only problem is that when I'm on a call, my cheek often times unlocks the phone, and does who knows what. I've added contacts, changed my location settings, all with my cheek and all without knowing it unitl after the fact.

I think it's because of the ability to wake/unlock the phone with a double tap. I'm running CM11 on this thing.

Does anyone know how to disable this?
