You have to also set SERIAL_PORT to -1, but both SKR V3 & EZ MCU variants compile fine under Windows 10 as well as macOS 12.7.4/Monterey.

We also use this board in our CI tests, so they would have failed.

Try performing the steps under the "PlatformIO Errors" troubleshooting section to reset & reinstall PIO.
