Is there a way to add new monitors on new masters without restarting sentinel nodes?

We are sharing one set of sentinel nodes to serve for multiple services. But the problem is once we need to deploy a new service, we need to add it to the sentinel monitoring, the old way was just add the master name into the ansible playbook, and rerun the tasks. But we found every time this task will restart our ansible. I wonder if this could improve if you detect the redis is already running, and only add the new masters using the command without restarting it.
