GA-Z170X-UD5 and Intel 600p M.2 RAID - can't do clean install of Win 10 Pro

[Skysis1]

I have a GA-Z170X-UD5 (BIOS version F6f) with a pair of Intel 600p SSD's installed.  I am able to configure a RAID volume in BIOS but attempting to install Win 10 Pro 64-bit to this volume hasn't been successful.  I boot to a UEFI USB, and I can get as far in the installation process as choosing the place to install the OS.  All attempts at loading RAID drivers (Intel's RST, Gigabyte's own Preinstall drivers) fail.  The drivers take ~5 min to load, then nothing.  Refreshing doesn't bring up the volume, and the install process continues to prompt for appropriate drivers.  Installation to a single SSD is flawless, and works well.  Any ideas?   Has anyone successfully installed a booting RAID with Win 10 Pro using this board and any M.2 SSD's?  Thanks in advance.

Greetings,
Have you reviewed the QVL for M.2 disks which support RAID?  Intel is not on the list.

It may be possible, but I'd start with disks on the QVL for best results.

You can try resetting the CMOS to defaults, configuring RAID (making no other changes) and trying the install again.  But the results might be the same. 

Another possible solution might be updating the FW on the individual drives, but this is more of a long shot.  Either you've missed something obvious, are not selecting the correct driver or have a compatibility hurdle.
