Intel FAQ had the following nugget of info but I've yet to try it

  What is the difference between Intel® VROC and Linux* MD RAID?
 Intel® VROC for Linux* is built upon MD RAID, and the Intel VROC team
 has an MD RAID maintainer on the team. However, Intel VROC has the
 following extra features:

 * Provides UEFI HII and UEFI Shell command line RAID management
 * Provides webpage-based, remote RAID management and RESTful APIs
 * Fully validated and supported with Purley platform and
 * SSDs Provides hotfix/patch to specific customer issue on supported OS

Seems a mess of licensing and enabling too :-(

Also seen this from HPE:

And this from Intel:
