The per-zone "forward" option is pervasive to all subzones of that zone.
This was done to solve the frequent problem of needing to disable
forwarding for all the subdomains of the local domain, while forwarding
everything else to a bastion host.

I believe the solution (untested) is to configure the subdomain as a
forward zone with an empty forwarder:

zone "sub.xxx.yyy.com" {
  type forward;
  forwarders { };
};

It will then follow normal delegation for that subdomain.

If you need this to happen for all subdomains of xxx.yyy.com, I don't think
there's a way to do it without listing them all in your named.conf.
