[PowerShell] Disable File and Print Sharing on Public and Private Network Category

I am looking for the right powershell command for Windows 2012 so I can turn off File and Print Sharing (in the advanced sharing options) for the Private and Public network categories.  I wisht to keep it on for the Domain Category. 

I have not been able to identify either a registry key or a powershell cmdlet that will let me do this. 

Any assistance is appreciated.
