I recognize that this is an old thread, but wanted to add something that I constructed using this info that I found handy. I used ACF to add a true/false field to user forms. I called it “show_custom_fields_admin”. Then I use the above code in conjunction with the value of that true/false field to hide or display the ACF menu.
function remove_acf_menu(){
global $current_user;
$show = get_field('show_custom_fields_admin',$current_user);
if (!$show){
remove_menu_page( 'edit.php?post_type=acf-field-group' );
}
}
add_action( 'admin_menu', 'remove_acf_menu', 100 );
When adding the true/false field to the user form, be sure to show it only if the user’s role is “admin”.
