Download this driver to a non-bootable USB drive.  Plug it in together with the Windows installation USB.  During Windows installation, at the screen which does not show any drive, just select load driver and browse to load the downloaded driver.  The Kioxia will be visible for installation.
My workplace recently ordered a Precision 7920 tower. The system shipped with ubuntu, but after awhile we decided to replace this with Windows. In doing this, I've been running into problems. The 4TB Kioxia NVMe drive that came with the system is not recognized by any installer, Windows, SCCM, or even Ubuntu. It shows up in the bios, but once booted into installation media it will not show up. I moved the drive to a different computer, and it was recognized immediately.  In the BIOS on both machines I have SATA devices set to ACHI and raid disabled, as well as intel VMD turned off for NVMe drives. Dell support would not assist as they shipped the system with ubuntu, and they told me they would not support any operating system that they did not install themselves, so I'm on my own here.
Drive not recognized when installing Windows.
