Yes. As you noted in your next post, if you specify O_NOFOLLOW | O_PATH when
opening the symlink, you will get a valid file descriptor.

You can then use that file descriptor to open the named attribute
directory via..
  namedattr_fd = openat(symlink_fd, ".", O_RDONLY | O_NAMEDATTR, 0);

This is minimally tested, but seems to work for ZFS and NFSv4.
