Virtualbox not working/support x64 VM on XPS15 9560 Windows 10 Pro 17025

I installed the Oracle Virtual Box to use Linux/Windows VM but when I try to define a new VM, virtualbox only shows the 32bit versions of OS.

But my laptop is aldready x64 and Windows 10 Pro 17025 also x64.

I checked the Dell BIOS and all items allready checked at the Virtualization Support menu.

So that I downloaded the Intel Processor Identification Utility and it shows Intel VT not supported at my laptop?

How is it possible and how can i fix/find solution?

I searched a little bit everybody said "you cann't see the x64 because you enabled the Windows's HyperV feature" so that you should uninstall the HyperV feature.

Is that correct or normal?
