How to disable/hide webradio?

Apologies if this has been covered in another post… I couldn’t find anything by searching the forum.

I don’t listen to webradio at all, and I’d like to hide webradio stations from the UI on my Volumio setup. Is there a way to do this? I find that the webradio stations really pollute my searches: most of the results of any search are webradio stations that I have no interest in. I’d like to limit to my searches to local music files (and possibly Spotify). Anyone know how I might accomplish this? I can’t find anything in the UI or by poking around Volumio configs via SSH.

EDIT: I’m using the latest version of Volumio for Raspberry Pi 3: v0.979
