Android Question disable (not only hide) the navigation bar

[vangogh]

hello
My app works in immersive mode, so the navigation bar is hidden, and the user can show it "swiping up"

the problem is that, using the navigation bar (show it by swiping up), the user can exit from the app... this is bad, as that device should be used ONLY for that app

can I totally disable the navigation bar, or control it?
The user will press a pwd protected button to exit the app

thank you.
