I don't know where you are getting enableEncryption/disableEncryption from. Those are not sedutil commands.

OPAL is more complex than just "enabling/disabling encryption" for a whole drive, and sedutil is a lower-level tool to manage a lot (not all) of what's part of the OPAL spec. As you can see in the output you posted, doing this is a multi-step process of enabling "locking ranges" and setting them into a certain state, and whatever else you want to do (like setting up a drive to be bootable from, or splitting a drive up into multiple ranges which can have separate passwords). Peruse the wiki of this repo!
