Restricting access to a course

Content

Is there any way to accomplish the following:

We have a course in a learning plan that has a rolling deadline once someone is assigned it. For example Employee A is assigned the learning plan with a due date 30 days from now; two weeks later, Employee B is assigned it with a new date of 30 days from that two week mark. If Employee A does NOT complete the course within their thirty days is there some way to block access to that course so that they cannot take it past their due date while also not blocking access for Employee B who still has two weeks to finish it?
