There is no option like that, as noted in the docs[1]:

=== Quote ===
Removal of zones provisioned using the autoprimary must be done on the
secondaries themselves, as there is no way to signal this removal from
the primary to the secondary.

You could have a look at Catalog Zones[2] in the latest releases of the
Authoritative Server.
Catalog Zones can provision and remove zones on secondaries[3].

Depending on the backend used, you can also switch to Native domains.
This means that PowerDNS won't do primary/secondary but the underlying
database does the replication of the data between the nameservers.
