There is not. Either bind does recurse, or it does not. If a DNS server is
authoritative-only, it is only contacted by other (recursive) DNS servers
that would (or, at least should) not trust what it says in ADDITIONAL
section of its responses (where the CNAME content in non-authoritative cases
belongs to).
