Technically OpenCV-Python could be built for Windows ARM. See instructions in the PR here: #644 (comment)
OpenCV team does not have Windows host on ARM right now for builds and testing. I'll return to the issue later in case of higher demand.

1. MSVC can cross-compile binaries on x64 hosts for arm64 target
2. Testing can be done on macOS M1 / M2 on Windows virtual machines installed via Parallel Desktops.
3. You can also consider purchasing this board and connecting it to github actions.

GitHub Actions now supports win-arm64 for free.
