Tablet [Q] SM-T210RDisable softkeys and enable in-screen keys

I have a rooted SM-T210R (GT3-7"), and they provided softkeys are VERY annoying to operate in the dark. Is there any way to disable them completely, and enable the regular Android soft keys? I have already verified Display options, and there's no option to do so in this model. Is there any hack to do so?
