How to make the ringtone volume control independent of the volume of other sounds in Android?

Question

Android

Is it possible to somehow make the volume of the ringtone and turn it off / on can only be changed through the settings menu, separately from everything else, so that by pressing the volume rocker it was impossible to turn off the call?
Ideally, I usually want to mute all apps, but keep the ringtone for phone calls - so that the phone makes sounds only in this case.
UPDATE:
In fact, I faced the opposite situation: I turned up the volume, there is sound everywhere, but the ringtone does not ring. I got into the settings, there is something like this, only I set "Music, video, games and other media" to zero, and "Ringtone" - more than half ... but it is silent ... it turned out that "Ringtone" although it has a separate regulator , but depends on "Music, video, games and other media" and is silent if it is turned off and to turn on the ringtone you have to turn on everything else.

Isn't there such a pimp?
Ringtone from flash drive?
If not from a flash drive, what are the access rights to files in / system / media / audio / ringtones?
