Has onyone gotten the BIOS in an HP Z4 G4 to recognize a Sabrent Rocket NVMe (M.2) 4.0 drive?

Hi Everyone, 

I can't get the BIOS to recognize my Sabrent Rocket NVMe 4.0 M.2 drive (2 TB).  Although it's gen 4, it should revert to gen 3.  The closest that the BIOS comes to recognizing it is that the M.2 bus speed changes from the default (2.5 Gb/s) to 8 Gb/s - so it must "kind of see it," since the bus speed changes.  The drive does not show up in the drives list for the Boot Order or diagnostic menus.  I've added two SATA drives at different times with no problems.   I've found the BIOS to be like nothing I've seen - clunky and complex and haven't had time to research all the pieces that might be impacting this (Security settings).  I also tried the BIOS troubleshooter and selected the option (2) related to drives not being recognized.  It only found my 3 SATA drives (2 SSDs and a mechanical HD) and the tests "passed."  For fun, I did try the partitioning util in Win10 and didn't see it.  I did call HP, and while the tech was very nice and patient, the line was "only HP drives are guaranteed to work").  Mainly we updated the drivers using their online resource.  Of course not helpful for a BIOS issue...  I have upgraded to the latest BIOS (2.56? from memory).  It came with the previous version, which didn't work either.  I did not try downgrading twice from here though.  I did pull the "imposter" brand RAM out, but didn't help either.

 

Thanks for your consideration.

PS - I forgot to mention that the BIOS hangs for 3.5 minutes before going into the setup screen with the drive installed.
