Htc m9 , can i disable the power and volume up button restart

AC Question

OK so I got an alarm to prevents me from turning off my phone so I would get up in the mornings as sleepy me thinks it's OK to miss col . Was working fine until half asleep me somehow figured out I could bypass this by holding the volume up and power buttons to restart my phone . I want this capability gone pronto, disabling this would be preferable as I have to much things to do and can't afford to be sleeping in . I would appreciate a solution
