Windows 10: Microsoft eDrive password

I brought a new SSD supporting SED. I want to enable it. But I saw someone said he enabled the function 'Allow OPAL Hard Drive SID Authentication' in uefi firmware, then he enabled Bitlocker. If he disabled the function in uefi firmware, the uefi firmware prompted a information that he must enter DriveLock password and could not enter uefi settings. Unless he unpluged the encrypted SSD. It seems that Windows automatically sets a DriveLock password but it does't tell the user. How to find this password. How to unlock SSD when the message appears.

Bitlocker eDrive not working well on certain notebooks

I am the owner of a Dell XPS with a TCG Opal 2.0 & IEEE1667 compatible Samsung 980 Pro SSD.

Before some of you will tell me not to use hardware encryption because of alleged weaknesses, I am aware of this paper and frankly modern Samsung SSDs were not affected as long as hardware encryption was utilized by TCG Opal. Also software encryption does lower performance, even with AES-NI.

That being said, there seems to be a problem with eDrive when used in Notebooks (such as Dell or XMG) that also allow you to set a password to NVMe drives via the UEFI: Once eDrive is enabled, the UEFI of the Notebook will pop up a password prompt for the eDrive enabled SSD. Obviously the PIN isn't going to work on the UEFI's password prompt.

You might ask "how is this a Windows/Bitlocker problem?".

1. If hardware encryption is used with sedutil, this problem does not occur even though sedutil locks the drive the tcg opal compliant way. If it works with sedutil I don't see why it shouldn't work with Bitlocker eDrive.
   
2. It happens on Dell as well as XMG notebooks and probably other brands as well.
   

I figure eDrive locks the drive in a way that makes it go haywire with the notebook's UEFI.
