Several users have requested the ability to register and initialize multiple CDC ACM instances, which would be used as serial backends for different subsystems. It should be noted that these instances will not be available for other configurations or USB device contexts. The order of the instances is also not guaranteed. For identification purposes, a host application needs to use the label property of the CDC ACM UART node. Signed-off-by: Johann Fischer <johann.fischer@nordicsemi.no>

Can you link to the source behind "Several users have requested the ability to register and initialize multiple CDC ACM instances"? The solution here is very questionable.

Is there anything specific to require having a dedicated Kconfig option? Why not just iterate over all zephyr,cdc-acm-uart compatibles?
