Your latest screenshots confirm that the SSDs are detected. They are listed under Intel Rapid Storage Technology rather than the normal NVMe Configuration page because Intel RST/VMD is being used.
The “Intel RST 20.1.0.5817 RST VMD Driver” shown in the BIOS is the firmware's RST/VMD component; it doesn't mean that the Windows installation environment has the required driver.
This is also consistent with Windows Setup showing only the USB stick.
I wouldn't change the RST/VMD settings, create a RAID volume, or format/delete anything at this point. On your Dell, download and extract the Intel Rapid Storage Technology (IRST) driver for the ROG Maximus Z790 Hero from ASUS. Put the extracted files on a USB stick.
Boot the Windows installer again and, at the drive-selection screen you showed earlier, select Load Driver. Browse to the extracted driver and load the Intel RST VMD Controller driver. Then see whether the Sabrent and your other three SSDs appear.
Your BIOS still has Windows Boot Manager (Sabrent SB-RKT4P-1TB), so I would also hold off on doing a fresh installation. If loading the VMD driver makes the Sabrent accessible, there may still be an opportunity to repair the existing Windows installation.
