Except we don't know what the CID is for those commands, do we?  I
didn't see it in the doc.

But just strip off the "MBB_" and we get:

1: MBIM_CID_MS_PROVISIONED_CONTEXT_V2
-- https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-provisioned-context-operations

2: MBIM_CID_MS_NETWORK_BLACKLIST
-- https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-network-blacklist-operations

3: MBIM_CID_MS_LTE_ATTACH_CONFIG
4: MBIM_CID_MS_LTE_ATTACH_STATUS
-- https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-lte-attach-operations

5: MBIM_CID_MS_SYS_CAPS
6: MBIM_CID_MS_DEVICE_CAPS_V2
7: MBIM_CID_MS_DEVICE_SLOT_MAPPINGS
8: MBIM_CID_MS_SLOT_INFO_STATUS
-- https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-multi-sim-operations

10: MBIM_CID_MS_DEVICE_RESET
-- https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-modem-reset-operations

Somebody print-to-PDF those pages quick.
