Pause a python multiple processes from multiprocessing.process and resume them using FastAPI

Question

I was trying to work something out with 3-4 python processes that run in parallel. I start/stop the service and interact with it using FastAPI. I wanted to add the functionality to pause the process (from multiprocessing.process) from the FastAPI dashboard and run it again by resuming it in some way. Is there a way to temporarily halt a python process? So far I could only terminate the process altogether. Thanks!
