Yep, software RAID is the way to go and Intel is advising you correctly.
There's no hardware RAID that will keep up with NVMe drives and although I believe vendors will be providing it, it will definitely be slower than software RAID.
Which begs the question, if you really insist on hardware RAID, why are you spending all that dough on NVMe drives in the first place?
