Haptic feedback instead of "touch sounds"?

On my Galaxy S7, under *Settings → Sounds and Vibration → System*, I have the option to - enable haptic feedback (vibration) for home-button, back-button and recents-button - enable "touch sounds", i.e. a clicking sounds when the touch-screen registers a press on a GUI button (automatically disabled when turning the phone to vibration mode or silent mode). Even on the lowest possible "System" volume, these are still a bit loud for an office environment. Is it possible, on Android in general or on the Galaxy S7 specifically, to replace the "touch-sounds" by haptic feedback? Note that the "keyboard" settings at the end of the dialog affect only the preinstalled Samsung keyboard (which I don't use), and not GUI buttons.
