Can I lock bottom touch buttons on Note 4?

[AC Question]

My father has recently got a Note 4, but as he only has the use of one arm due to suffering a stroke, he is forever accidentally hitting the bottom 'invisible' touch buttons when he tries to type. I was wondering if there was any way to 'lock' these buttons? Thanks in advance.

Welcome to the forums. It may be possible with rooting the device to render them unusable. I am not totally sure though, it has been quite some time since I used a Galaxy product.
