Mouse side middle buttons needs to be disabled. But how?

I have an annoying issue, the side buttons of the predator mouse are located right in the middle on the bottom left side on the Predator P03-600 Deesktop model , My two little fingers keeps on knocking against those two middle buttons putting pressure against then whenever  I try to drag the mouse over across the screen, causing other windows to open up at the same time when trying to drag the mouse pointer because those two side buttons keep clicking.  Not good design to place the two middle mouse buttons right in the center.  It should've been placed much more lower down on the bottom of the mouse so the little fingers don't press against it from dragging the mouse.  I'm one of those users that like to rest the little fingers against the left side of the mouse because a mouse that is not wireless puts tension on the fingers when dragging the cord all cross with it  and I can't do that with this predator mouse. Because the buttons are in the wrong place, that placement of the buttons is designed to suit wireless mouses.  So they put a cord on a wireless design which defeats the whole purpose.  So I have to disable those two buttons to stop it windows from popping up other windows when dragging across with it.
