As I understand it, the ‘multiprocessing’ module
<URL:https://docs.python.org/3/library/multiprocessing.html> does not
create multiple threads; it creates multiple processes.

It also closely follows the API for the ‘threading’ module. That
includes the ability to manage a pool of workers
<URL:https://docs.python.org/3/library/multiprocessing.html#module-multiprocessing.pool>.

You can ask the pool of workers to close when they're done
<URL:https://docs.python.org/3/library/multiprocessing.html#multiprocessing.pool.Pool.close>.
Does that address the requirement?
