Do not try to write data to the drive, it'll just wear the drive out a 
bit and won't actually accomplish what you're trying to do.

Install the nvme-cli package and use something like (this will destroy 
the data on the drive, don't play with it):
nvme format -s1 /dev/nvme0n1
the -s1 triggers the drive's secure erase functionality.

If you're lucky that will work. If not (some manufacturers are more 
trouble than others) you can look for a workaround.
