Sales Order Lines Update getting failed from Rest API response Immediately after order created

Summary:

We are facing issues while updating the sales order line using Rest API (From OIC) immediately after creating the line. Observation is that when fulfillment line status is "NOT_STARTED" or "CHANGE_PENDING" that time we are not able to update the line from OIC using Rest API and it gives error, and order goes into Draft status.
As discussed with Oracle support over the SR for same concern we received the information that put wait between Create Order/Line and Update Order/Line (Currently both are happening within 8 seconds).
Now, we have following questions.
We would like to know how to make sure that orchestration is not progressing that line when we try to update the line.
