How to update celery code?

Question

Celery

I have a small flask project that uses background tasks using celery. The tasks themselves can take several hours to complete. Supervisor is used as a daemon for celery.
The problem is that when updating the code on the server, celery executes the old version of the code. It is impossible to restart ( supervisorctl restart ) each time the supervisor, because there are many tasks and they run for quite a long time.
Is it possible to update the code without rebooting the supervisor?

Of course no. Choose a time when everyone will stand and overload.
