It is possible to export and import Settings in a Json file using the ACF > Tools menu. Settings can also be exported in PHP format, to manually register them in the functions.php file. Those tools are also available directly within the Settings UI sidebar.
ACF Extended use the native ACF setting show_admin to determine if the module menu should be displayed or not. You can read more about that setting on the ACF article How to hide ACF menu from clients. Usage example:
add_filter('acf/settings/show_admin', '__return_false');
