Lots of info online about “You got a Windows 11 preinstall, well you can install Windows 10, no problem.” Some articles had conflicting information saying you would need a downgrade kit or something.
So when in doubt, just try it yourself. I downloaded the stock Windows 10 Media Creator and made an ISO and loaded it in a VM. At the product key prompt I added my Windows 11 sealed OEM key and it continued the install.
