How to run an app and process only on the efficiency cores for apple silicon.

Okay, so title says it, I'm wondering how to do this. I have cinebench on my mac and for fun I want to run it only on the efficiency cores just to see how powerful the efficiency cores are. Would there be any way for me to go into the code and tweak it to be the background parameter qos and would that make it run on the efficiency cores only? And where in the code would I go in the app? How would I make cinebench only run on the efficiency cores?
