I have a Latitude 7490 with a M.2 512GB PCIe MVMe Class 40 Opal 2.0 SED Drive.

With past SED drives, I could enter a hard drive password in Setup which would needed to be entered prior to booting the system.  This password stayed with the drive so decrypting still required entry of the password if the drive were removed from the system.

There is no option for a drive password in BIOS and hence nothing to enter prior to boot, unless I put in a system password.  I assume that the data is encrypted on the drive, but am not sure that the data would be inaccessible if the drive were removed from the 7490. Is the encryption tied to the specific system so the drive is unusable elsewhere? 

I've done some searching but can't seem to locate definitive information about this particular type of SED
