Which you can't do even on a developer unlocked device, with an admin command prompt or PowerShell. It simply won't work as has been stated twice before.
Like I said, the only way you can do that is with a company account and a policy distributed through MDM on a Windows Server. That is the ONLY way you can do what you are asking.
