How would having a free period/early release at the end of the day affect college admissions?

I am attempting to get into a competitive college and I am set to take four AP classes (maximum my school allows or offers) this senior year. However, I am planning to go to a tech college, therefore I would like to drop my last class, AP Biology as it really doesn’t align with anything tech related and it would lower my workload, allowing me to focus on other clubs, how would dropping that class (before school starts) affect my chances of getting into a competitive college such as UC Berkeley?

Wow I am taking four APs including AP Bio and have early release and late arrival as well. It would probably be a good idea to keep Bio.
