Apple Silicon Macs (like M1) do not support Bootcamp so that's not even an actual option.
They also do not support the regular x64 Windows version and require you run Windows for ARM.
You can try to simply update your existing Windows 10 installation to Windows 11 from inside Windows using Microsoft's software update but you'll likely need to jump through several hoops as its not officially supported and will balk at the lack of TPM chip. 
Also, you'll need a valid Windows 11 Key as Windows is not free.

I assume you are currently running Windows on Parallels or some other virtualization software solution that let's you run Windows on an M1 Mac.
