To partially disable the Hyper-V time synchronization provider, leave Time synchronization enabled under Integration Services and run the following command from an elevated command prompt on the guest domain controller:

reg add HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\VMICTimeProvider /v Enabled /t reg_dword /d 0
