How to do pause syncing using powershell script or command line?

[Avian 1]

We are in process of upgrading machine W7 to W10. We want to delay or pause sync for 2 hrs until all W10 ugradation is not completed. Is there any way to delay or pause sync for next 2 hrs thru command line or thru PowerShell script? I know this can be done thru manual approach, but I want to make this as automated process. 

Please advise

I'm not aware of any powershell script or command line switch to make this happen. Perhaps you can remove the client and re-install it after the update is complete?
