We have a lab setup where we are testing a customer configuration but do not have all of the same equipment.
Is it possible to have a bind server that resolves certain FQDNs in a zone, while forwarding the remaining to another DNS?

We tried putting forwarding in the zone, that did not work, seems to forward all. All other types of zones would not work either.

not with BIND. Bind either forwards, or resolves. If it resolves, it is
authoritative - if it does not have the answer, then the answer does
not exist. You can use lightweight DNS servers like dnsmasq that can
locally resolve some hosts and forward all the rest.

Not easily. You could create a zone per FQDN you want to resolve, or use
RPZ to re-write query responses in bind 9.8.

It sounds like you want something similar to "local-data" in unbound
