Is none the correct Linux I/O scheduler to use?

We have got a few new Intel P3700 800GB NVMe Gen3 PCIe SSD cards. We put them into a few brand new servers and kickstarted them with CentOS 7. After installation, I was surprised to find that

[root@sc2u0n0 ~]# cat /sys/block/nvme0n1/queue/scheduler

none

I couldn't find this scheduler option anywhere, definitely not from https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/block/switching-s... the official Linux doc on kernel.org. Can anyone confirm that this is the correct setting? Or if not, do I need to change it to say noop?

Thanks,
