arp authorized is IMHO proper command for disabling ARP learning on
(sub)interface....

From documentation:
To disable dynamic Address Resolution Protocol (ARP) learning on an
interface, use the arp authorized command in interface configuration
mode. To reenable dynamic ARP learning, use the no form of this command.
