Question m.2 os boot with ssd raid

[screenwatcher99]

I recently just finished my build. I have an NVME drive that I loaded windows on. I also have 2 2tb 2.5" SSDs that I would like to put in raid 0. I cannot find this option in the bios. I can only disable their sata port but I can't find where it says that I can put these two drives in raid. I have a maximus XI formula. my NVME is an samsung 970 pro. And the two SSDs I would like to put in raid are western digital blues.

UPDATE: Inside windows I opened disk management and noticed that I had two volumes. the M.2 at 476 GB, and the couple SSDs are apparently already in raid because it lists only one other disk with 3.7 TB of storage. however....1678 GB of that storage is unallocated and I am not able to create a simple volume or extend the other volume. Are there any fixes on this?

MBR partition style limits usable space to 2TB. You have to change partition style to GPT.

Personally - I'd just use those drives without any raid.

I tried deleting the volumes so I could change the style to GPT, But I have a "Healthy (recovery)" partition that I can't delete.
Is there another way to change it to GPT?

You'd have to use diskpart to delete recovery partition. Disk Management normally would not allow that.
