Don't list the primary server in the NS records for the domain.

What do you mean by "both primaries"?  There's just one primary.  All the
other servers are secondaries, and they're listed in the NS records.

A hidden primary is just a primary server whose existence isn't advertised
in NS records, so no one will send queries to it.  The secondary servers
have its IP address in their configuration files, so they do zone transfers
from it.
