How to hide plugin fields in WordPress editor?

Question

WordPress

Can you please tell me how to hide the fields generated by the plugin in the WordPress editor?
Is it possible to create a custom CSS file that will override plugin meta box styles?

It's about the Tutor LMS plugin. There, when creating a course, there are extra fields in the editor.


I also tried using functions, but it seems I am passing the wrong parameters ..

function remove_post_custom_fields()
{
  remove_meta_box('tutor-metabox-course-settings-tabs', 'post', 'normal'); 

}
add_action('admin_menu', 'remove_post_custom_fields');
