sedutil - The Drive Trust Alliance Self Encrypting Drive Utility

This program and it's accompanying Pre-Boot Authorization image allow
you to enable the locking in SED's that comply with the TCG OPAL 2.00
standard on bios machines.   

You must be administrator/root to run the host management program

In Linux libata.allow_tpm must be set to 1 for SATA-based drives,
including NGFF/M.2 SATA drives.Either adding libata.allow_tpm=1
to the kernel flags at boot time or changing the contents of
/sys/module/libata/parameters/allow_tpm from a "0" to a "1" on
a running system if possible will accomplish this. NVMe drives
do not need this parameter.

***** sleep (S3) is not supported.
