Don't think there is a routine to switch between navigation buttons and navigation gesture bars, but you can turn "Assistant menu" (which has home, recent, back button) on in "Change settings" for your driving mode.
Or, use "One hand operation+" to set up a swipe action to "show/hide navigation bar"
