How to Hide Project DFFs in Responsive Self-Service Procurement?

Summary:

In RSSP, we would like to hide the 'Contract Number' and 'Funding Source' fields in the ProjectDFFRegion in any and all screens/operations. See attached screen shot for where these two fields appear in the ProjectDFFRegion.

Reviewing the documentation for 24B, like that below, I had thought it would be possible. However, I have looked everywhere and tried everything I can think of, including duplicating default Business Rules, Rule Sets and Layouts, but have had no success.

Thank you in advance!
