Hi AJ,

You could just enable only the Guest enrolment plugin on those information courses. And turn off the "login as guest" button on the login page

Site Admin-> Plugins-> Authentication->Manage Authentication, set "Guest login button" to "Hide"

That way random external people will not be able to log in to your site, or see the info courses, but your registered users will be able to access those courses as Guests once they have logged in, which means no completion tracking will happen and the courses should not show up on the Record of Learning.
