I’m looking for information on whether or not EOS supports BGP add-path for VPNv4 and VPNv6 address-families.

Let’s observe that design wise add-paths is not needed for VPNvX AFs. Those AF’s NLRIs already contain RD which makes prefix they carry unique. The only requirement is that you use either auto-RD feature or unique RD per VRF on your PEs – which by itself is a good and recommended practice anyway.
