Hello, Could someone explain more about

Version Locking

is it saying enforcing the assertion that a submitted/triggered flow run would run once and only once?

<https://docs.prefect.io/orchestration/concepts/flows.html#toggle-version-locking>

Yes, this is correct. Since prefect flows run on your infrastructure (and various infrastructure backends can trigger restarts), we use version locking to ensure that only one version of your flow run is ever running at a time.

Got it. Thank you. Is this flag turned on by default? If not, how do I enable it in my flow.register code?
