Well, if you did 3min research and checked out the mentioned DL schools, you'd know the answer. Anyway..
BUT, nothing prohibits you from making headstart by finding some resources online or lending/buying some books to study from. If you don't have PPL yet, I think it makes more sense studying for the PPL first, going for basics, then more advanced stuff. If you're geeky and know it all already, then why not reading up ATPL stuff?
The catch is, in modular, you can't be officially enrolled on the course.
Had I been one of those 'cadets' these days, I'd have found it pretty damn boring to read tons of stuff I can't relate to ('just yet'). Would anyone sane pass all the PPL exams before going up in the air for the first time? So why ATPL?
