-        <help>Exclude this item from the HA synchronization process. An already existing item with the same UUID on the synchronization target will not be altered or deleted as long as this is active. This option can be helpful when using Unicast CARP. After the initial synchronization, enable this option and adjust the Unicast IPs on the backup firewall. Additional IP aliases in the same VHID group can now be synced without overwriting their parent CARP VIP.</help>
+        <help>Exclude this item from HA synchronization. Enable manually for the same item on both master and backup to prevent changes, deletions, or syncing. If this setting is removed from the backup but kept on the master, the item will be deleted on the backup during synchronization. Useful for Unicast CARP: after initial sync, enable this and adjust Unicast IPs. Additional IP aliases in the same VHID group can then sync without overwriting their parent CARP VIP.</help>
