Hypervisor on VBox

I installed Vbox and running Windows 10 on it on my Mac book air , 2017 model.

I'm able to enable Hyper-V on Windows VM, but not Hyper V - Hypervisor. (attached screenshot)

When I hover over the option it shows "Hyper-V cannot be installed: The processor does not have Second Level Address Translation (SLAT) capabilities.

I've tried BIOS setup on windows 10, unfortunately, the options weren't popping up.

I'm not sure if something has to be changes in Host (MAC) or the VM.

Any help will be appreciated.

Thanks
