How to mount raw device？

[HeyLK]

PV.yaml and PVC.yaml setting "volumMode: Block" does not take effect.
When the fstype of the disk cannot be obtained, it will be formatted as "ext4" by default and cannot be mounted as a block device.
How can I mount a disk as a block device?

sorry for the slow reply.

Right now, our NVMe-oF CSI driver can't mount block devices. I gave it a shot with mounter.Mount in pkg/nvmf/nvmf.go but ran into some issues.

I've got this on my list to tackle next month.
