How to install Windows 11 on a bare metal system with an unsupported CPU and without using the installation bypasses?

On one hand environmental sustainability is important to Microsoft:
https://www.microsoft.com/en-us/corporate-responsibility/sustainability

On the other hand, they don’t seem to care.

There are only 8 7th gen. Intel i-series CPUs on the list of supported processors for Windows 11 and no 6th gen. or older Intel i-series CPUs:
https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-intel-processors

In my opinion this goes against what Microsoft has stated for their sustainability commitments, i.e. you are not able to upgrade the OS on a Windows 10 computer when Windows 10 reaches end-of-life and you need to purchase a new computer for Windows 11.

Microsoft has made a comment about this issue in Installing Windows 11 on devices that don’t meet minimum system requirements but to me the comment should be either “Yes, it works” or “No, it doesn’t work” instead of “Devices that do not meet these system requirements will no longer be guaranteed to receive updates, including but not limited to security updates.”
