Other How to disable Volatile Write Cache in NVMe drive?

[Sagara W.]

Hi

I'm on FreeBSD 12.1 with a M.2 NVMe card.

nvmecontrol identify nvme0
NVM Command Set Attributes
Volatile Write Cache: Present

Many thanks.

Best regards
Sagara.

In other words, I'm looking for the feature similar to wcache-sct of smartctl(8).
