Nope. Switching this off can be harmful. Suppose Slave A has lost
connectivity to the master server but could have received a NOTIFY and
done a zone transfer from Slave B. Would it be better for A to hand
out stale data for the zone or retrieve an up-to-date version from B?
Leaving NOTIFY switched on -- BIND's default behaviour -- is harmless.
