I was wondering if Windows 11 arm can be installed on Redmi note 11 with snapdragon 680 through this project… and If not which CPUs or models from xiaomi are fully supported?
Theoretically a lot of things are possible. SDM 680 SoC is not ported to UEFI, so even before porting the device to uefi itself, you need to port the SoC. There is currently no documentation in how to port SoC, so goodluck.
