Can the navigation buttons be hidden on home screen?

We can not hide the Nav buttons on the Home Screen through the native software. Need to use a Launcher like Nova.
We can only use native software to hide the Nav buttons while in Apps or app menu.

Right now I'm having trouble with my nav bar not sticking, particularly in messaging and on Facebook. Any thoughts on how to fix it? Double clicking does nothing. I'm on Mica Launcher but this just developed this morning.
