I don’t have a WD NMVe SSD so I cannot test the following myself, but I don’t suppose it’s possible to simply boot Hiren’s BootCD PE via Ventoy or the like and then run the official for-Windows WD SSD firmware updater?
I recently had to do this to update the BIOS on a Thinkpad from a friend because the ISO image Lenovo provides was unable to be booted for some reason when using Rufus, Linux Mint’s “image writer”, etc (it’s possible that this was actually a BIOS bug because one of the newer BIOSes mentioned fixing being unable to boot from USB in some instances).
