Fedora 34, cannot disable media keys

I’ve installed fedora recently and I have a problem to disable media keys. I used dconf-editor and I removed there any binds to media keys for audio play/pause/next/prev volume raise/lower/mute but it doesn’t look that make any difference. By pressing volume up/down still the gnome’s OSD for volume control pops’ up and the volume change. Also media keys which should be available to configured actions in kodi don’t work.

Welcome to ask Fedora.

Please give us more information about your system and also about the keyboard.
A good help might be the #start-here topic.
