I tested Rufus. Installation by running setup.exe worked but automatic installation did not work without manually clicking.
setup.exe /ShowOOBE none /EULA accept /Compat IgnoreWarning /auto upgrade /DynamicUpdate Disable

I then tried Patchium but the installation stopped and Secure Boot was required.

Edit:
The problem was with a ISO image created by Media Creation Tool. When I downloaded the ISO file directly from https://www.microsoft.com/en-us/software-download/windows11 and used Patchium. Installation did not require Secure Boot.

Edit:
Cannot update Windows 10 22H2 to Windows 11 24H2. I get complains about TPM 2.0 and Secure Boot. My first test was to update Win 11 23H2 to 24H2 and it was ok.

Edit:
I'm updating Windows 10 machines to Windows 11 23H2 which is supported till November 11, 2025.

Edit:
The issue with Rufus setup.exe is now fixed pbatard/rufus#2752
