The only information I found was on the Executive Order signed by President Biden on 18 November 2021: Executive Order on Nondisplacement of Qualified Workers Under Service Contract.  Here is a link:  https://www.whitehouse.gov/briefing-room/presidential-actions/2021/11/18/executive-order-on-nondisplacement-of-qualified-workers-under-service-contracts/ 

If you read the Executive Order it provides some of the information you seek. 

I strongly recommend you consult with your Contracting Officer and/or Legal Office to gather more information on this particular question.
