Project acutalize

Hello, would like to ask.
I have a NR project and I am running the same flow on the same machine in more instances (more ports)
And I am interest in following:
When I did some update on one of the instance, create a commit.
Then I would like to implement changes on the other insancies. they are reading the same flow, so basically it would be enough to restart flows.
How can I do it programmatically from them? Is there some trigger or RED function which can I call to restart it?
Or there is some other possibility how to implement changes on all instances/ machines which are using the same flow?

Thank you
Pavol
