How to upgrade Windows 10 to Windows 11 on Mac via Boot Camp?

I have been using Bootcamp to run Windows 10 on my MacBook Air for years and no problem with it. It comes with an Intel i5 CPU 3.6 GHZ,  256SSD and 8GB RAM. I think it is still powerful enough to run Windows 11. However, I couldn't find an option to for upgrade. I double checked the Windows Update section and the latest version available for install is Windows 10 22H2.

How can I upgrade Windows 10 to Windows 11 on Mac in Bootcamp and I hope the upgrade could retain all personal files and apps. Is this possible for MacBook Air?
