The BIOS's may never support hardware encryption on nvme drives, however you don't need it. See sedutil for a software solution to setting the password for the encryption key. No special BIOS support is required.

Beware of Asrock, at least when you have a Z370 board! Their latest UEFI updates for these boards which also include a newer Intel SATA rom completely kill the compatibility with hardware encrypted (SATA) drives. If you update for example a Z370 Pro4 to UEFI 3.30 and have ANY hardware encrypted (Bitlocker edrive) SATA drive connected, the board WILL NOT POST! It is enough to just have such a drive connected for the UEFI to fail. It is not related to the boot drive. You can't even access UEFI setup in that case. You will quickly see the Asrock logo followed by immediate black screen and it does not respond to any keystrokes anymore. Only workaround is to disconnect all Sata drives which have Bitlocker hardware encryption enabled. If I disable Bitlocker before updating the UEFI, it does post and boot without problem. If I enable Bitlocker again, black screen and no post. Tried it with different SSDs and Sata ports, does not change anything. I talked to Asrock support about this, and they told me that they were in fact able to reproduce this issue. They told me the only possibility for these boards after doing the UEFI update is to DISABLE Bitlocker edrive hardware encryption, otherwise the UEFI will not post and it is thus impossible to boot. See the original response from Asrock below. I was really surprised about such a statement. Initially I thought there might have been a misunderstanding, because I couldn't imagine they are really telling me something like "just don't use it anymore, it does not work", so I asked them again if they are serious about that. But they confirmed that statement and said they can't do anything about it. @Asrock support wrote: Hello, feedback from BIOS department: After checking and experimenting, we get below conclusion regarding hardwareencryption Bitlocker. If the system is under encrypted status, it cannot boot into Windows again when restart system. Only re-install OS or remove encrypted HDD and then able to boot properly. So, please decrypted hardware encryption before shut down or restart system. Then system is able to work normally. best regards, ASRock Support ASRock Europe B.V.
