EDIT: OK, Odyssey already found about fake location, see Fairphone 6 GPS stopped working - #2 by Odyssey
You might want to have a look into /e/OS Advanced Privacy. You can find it on the screen to the left of the home screen.
Advanced Privacy includes the option to not submit your correct location to apps (right now I do not know if this is the default). You can either allow all apps to see your correct location – or exempt certain apps from the false location other apps are getting.
