trying to keep two emails from syncing accounts

Hi, I currently pay for After Effects, but my school is going to have us use the school trial of photoshop.

Every time i download photoshop and sign in under my school email, it links my paid after effects account to my school email. I do not want my school account linked to my personal account. Is there a way for me to have two accounts with two different email and prevent them from syncing?

thanks!
