Disable option for WPML footer language switcher

Summary

In WPML there is a setting to show a language switcher in the footer or not (see screenshots), right now if it's shown it looks really ugly, since we don't have a specific design for that. We can disable it for now to avoid confusion.

Requirements

• Check if there is a hook to completely disable that language switcher.
• Alternatively we could use css to hide it on both backend and frontend.
