It isn't possible to have Xerox Features and not be on MacOS 10.15 with any driver from 4.0 and up.
The 3.X drivers don't support AltaLink so they can't be used either.
Apple introduced library validation and that made Xerox features turn back to printer features, they fixed it in the release of 10.15.
