I think so. If you disable notify by default - use a "notify no;"
clause in the options{} statement - your master name server won't
send notifies. Zone-specific notify clauses can then be used to switch
on notify processing. So, that way, the master server could/should be
configured to only send a NOTIFY to dns1.my.domain.com and that can
send NOTIFYs to dns[234].my.domain.com. Make sure that the name
servers that get sent NOTIFYs have the address of the server that
sends the NOTIFYs in their masters{} clauses. ie. That clause on
dns1.my.domain.com should have an entry for the IP address of
dns0.my.domain.com. The relevant zone{} statements in named.conf on
dns[234].my.domain.com should have entries for dns1.my.domain.com.
For [2], named.conf's also-notify clauses are your friend....

Personally, I don't see the need for this complexity. Why wait for
dns1 to update the zone and send NOTIFYs to the other name servers?
What is the benefit of this extra overhead? Why not let dns0 send them
to all the zone's servers so that the zone updates can be propagated
everywhere at once?

PS: PLEASE don't use invented domains like my.domain.com or fake IP
addresses when you post questions to this list. Always use the actual
names and addresses. For one thing, it makes troubleshooting easier.
It also makes it a lot easier to provide clear answers when the real
domain names and addresses can be quoted rather than abstract,
invented ones. And sometimes those made-up names or addresses really
do exist. For instance, the domains mydomain.com and example.com
*really* exist.
