If you mean OpenPGP Card v3 standard, no it did not support cv25519 ed25519, but some other curves up until v3.4. So if there is a specific specification bringing this feature, can you might refer to the specific version? Otherwise, I think this task is still valid.
I remember the problem being the card manufacturers that are not interesting in cv25519 (yet).

You are right, the new 3.4 cards support brainpool curves in addition to the nist curves.
