Leave Win10 Insider Preview program, programmatically?

Question

Hi All

I have found several win10 machines on 10.0.19042.508, which i believe is insider preview channel.
Now i have found articles to show how to leave this program manually.

eg. https://support.microsoft.com/en-us/windows/stop-receiving-insider-builds-for-windows-10-be2c37cf-ae6e-c654-a6df-b3ebbcdc3404#:~:text=Select%20the%20Start%20button%2C%20then%20select%20Settings%20%3E%20Update%20%26%20security,to%20opt%20out%20your%20device

However, does anyone know if this is possible to do programmatically? such as powershell?

Thanks
DM
