Asus Memo Pad HD 7 navigation button. topic

Hello, I am trying to remove the extra navigation bar button that seems to come on all Asus Android tablets. Its not the 3 standard buttons, but the one all the way on the left that opens a menu for "miniapp docking". I uninstalled the miniapp docking system app but the button still shows up on my nav bar. Is there any way to remove this ugly button?
