Is it possible to evaluate the impact of my changes to the architecture without waiting for hours?

I am a computer science undergraduate student, currently developing skills in deep learning. My current project involves training a facial emotion analysis model. I regularly make small changes to the architecture to improve the model's performance. Unfortunately, every change necessitates model retraining.

I'm curious if there is a way to evaluate a change without enduring hours of retraining.
