Hi,
TFS (nowadays known as "Azure DevOps Server") is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).
You can ask the experts in the dedicated Azure DevOps Server forum over here:

Best regards,
