[Q] Anyway to remove Task Manager/Close all from Recents? topic

Every time I open my recent apps it becomes a game of Operation to try and not hit either the Task Manager or the Close All buttons while scrolling or reaching for the hardware buttons. It's infuriating to work on my phone and have to worry swiping those two. Anyway I can remove them?
