dns_lookup_kdc=false in [libdefaults] should suppress all SRV lookups by
libkrb5 for realm KDCs, whether or not there is a [realms] section for
the realm.

In your scenario, it's possible that a locate plugin module is taking
care of the lookup.  This explanation is more likely if the system is
running sssd.
