Method 5 – Easy switching between 2 modes
C:\>bcdedit /copy {current} /d "No Hyper-V"
The entry was successfully copied to {ff-23-113-824e-5c5144ea}.

C:\>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off
The operation completed successfully.

OR

bcdedit /copy "{current}" /d "Hyper-V"
bcdedit /set "{current}" hypervisorlaunchtype off
