How do I override sub dependencies using only requirements.txt?

I'm trying to deploy my python app, and my first step was to try and dockerize it. My project needs fastaudio 1.0.2 and fastai 2.7.9, but fastaudio 1.0.2 needs fastai == 2.3.1 as a sub dependency. I was able to override it during development by simply upgrading fastai after installing fastaudio. Is there any way to override this check by only editing my requirements.txt file?
