How to disable role notification during battlegrounds?

I've pretty much checked everywhere in the System and Interface game settings but i couldn't find one. I've tried as well disabling my ELVUI addon and unchecked the System messages option in Chat settings, but still the same. Not sure if this is hard coded, or it can be disabled by a script. Didn't have this role notification before though.

Turn off Auto Role set from ElvUI Chat Tweaks.
