That doesn't quite seem like an answer. Can I put in a fake address? If I put in a real address, will the platform decide to spam me?

Like, can I use https://temp-mail.org/en/ or will I need the email to access the material at a future date?

Yes you can.

Just put in ANY valid email. They don't even ask you to confirm it before starting the course. I generally use https://www.yopmail.com emails, works fine.
