I'm using LearnDash for a course that is drip fed by week. The subforums follow the lessons and are embedded as shortcode on the lesson page.  I don't want students to be able to access any other subforums or the entire forum anywhere else except through the subforum shortcode on lesson pages they already have access to.  This is to keep them from jumping ahead to subforums that belong to a future lesson. I could not find a setting to do that and there seems to be all sorts of ways and links to get to the main forum and other subforums.  Is there a way to do what I want?
