Cannot boot to Software RAIDED NVME Drive (Asus Prime Z270-A)

I am currently having an issue booting to RAIDed drives with Rockstor installs, not only can I not boot to a RAIDed NVME device (Corsair m500), I am unable to boot to installs placed on RAIDed SATA HDDs (WD 8TB Reds). I have attempted on drives RAID 1 & 5. The nvme drives are seen by the installer, but not when RAIDed. Has anyone successfully installed and booted to RAIDed NVME drives using a z270 motherboard?
