Is there a way to set the acks_late config in Celery?

For my Django project, I am using Celery with Redis, registering the tasks on runtime using the celery_app.tasks.register method. I want to retrigger a task in case of some failure, I have set the acks_late config param using task_acks_late=True on the app level while instantiating celery itself. I have also set task_reject_on_worker_lost=True. However, the tasks aren't being received back by celery no matter what. Is there any other way?
