Per Synology's recommendation, MPIO should be preferred over bonded interfaces for iSCSI, how is this configured?

According to this KB entry
https://kb.synology.com/en-global/DSM/tutorial/How_can_I_troubleshoot_iSCSI_storage_performance_issues
MPIO should be used for iSCSI connections, to increase the available bandwidth for all hosts.

It is recommended that you configure MPIO instead of network bonding (or Link Aggregation) to maximize the throughput for all hosts.

How would I configure MPIO in the CSI layer? I am aware I can add multiple NAS hosts during configuration, but afaik this is used to allocate storage on different NAS devices.
