For the adventurous, you can probably make/hack something yourself with
unbound-control local_data /RR data/.   With local-zones, Unbound is
"authoritative" for the RR data in a zone.  (Note there are different
modes for local-zones: transparent, redirect, deny, etc.  See man pages
of unbound and unbound-control.)
