Bypass oem key for a clean install

If I have a laptop with pre-installed Windows 11 Home and I want to format and clean install Windows 11 Pro with the official Microsoft multi-edition ISO,

I surely have the oem key of Windows 11 Home in the hardware so Windows will install the Home edition without ask any Product Key,

I want to avoid to upgrade later to the Pro edition,

It's still a solution to create a file named "ei.cfg" with the text:

[EditionID]
Professional
[Channel]
Retail

or

[Channel]
_Default
[VL]
0

and put it into the "Sources" folder of the USB support?

Ei.cfg works.
