Shortening an Amazon SDE internship

Is it possible to ask to shorten the length of an Amazon SDE internship from 12 weeks to 10-11 weeks? I have a co-op for the fall, but I have an interview coming up with Amazon, and I am curious to know if people have been able to ask for shorter durations for Amazon SDE internships because of other commitments (internships, classes, etc) as I want to know if that'll affect a potential offer. Thank you! Edited to say I have an interview coming up and that’s why I am posting haha
