Hi,
The hidden options of HikaShop are still valid.
However, the value "no" was not supported and is still not supported.
The supported values for the hidden option "font-awesome" are "local" "cdn" and "none".
Note that instead of completely deactivating font-awesome, which will cause issues in your backend since it uses font-awesome, I would rather recommend to add an entry with the namekey font-awesome-type" with the value "admin".
That way, font-awesome will only be loaded in the backend and not in the frontend.
