Windows 10: Downgrade to Win 11 pro without serial licence number OEM pre-installed Win 11 pro before

Hello,I recently purchased 3 computers that came with a pre-installed version of Windows 11 Pro. The computers were already configured with an administrator local user session without password, it was not good for me. I manage these computers using Intune. I try to reset it but it says missing files. Following Copilot's advice, I created a Windows 11 ISO key and formatted these computers. During the setup of these new systems, I entered the Intune user acount. Once everything was configured for the 3 PC, I realized that the versions of Windows 11 used are Enterprise Business versions not

Clean install of win 11 pro

I have a laptop running with a digital licence for Win10 Pro. The laptop originally came with Win 10 home but I upgraded to win 10 pro using a key from a win 7 ultimate dvd.

Windows update tells me I can update to win 11 pro from my present install and acquire a digital licence from MS.

My potential issue after doing so would be, if I wanted to do a clean Win 11 Pro install after getting the digital licence (for win11 pro) I suspect the install would read the bios key and install Win 11 home and not Pro. Apparently Win 7 keys are no longer valid for the Win 10 and 11 upgrades.

My question then becomes what steps do I follow to do a clean Win11 Pro install on this laptop bearing in mind the system came with Win10 Home.

Thanks in advance for any guidance.
