Adding extra NVMe drives to PowerEdge R6515

Hello

I have server  PowerEdge R6515 10x2.5 enclosure with controller 940P . I have 2 SSD SAS drives in RAID1.

As per the manual, I can install 2 x NVMe drives in slots 8 & 9.

My question will the 2 NVMe drive be added to the RAID or will they appeared as separate drives than the RAID.

I want them to be non RAID then can install ZFS file system.
