How to fix Dismount-VmHostAssignableDevice issue?

Question

PowerShell

I am trying, according to this article , to forward PCI-WiFi to a Hyper-V virtual machine.
Faced such an error.
PS C:\WINDOWS\system32> Dismount-VmHostAssignableDevice -LocationPath $locationPath -Force -Verbose VERBOSE
: Dismount-VmHostAssignableDevice will disable the assignable device so it can be assigned to a
virtual machine.
Dismount-VmHostAssignableDevice : The operation failed.
The current configuration does not allow the OS to control the PCI Express bus. Check your BIOS or UEFI settings.

In the BIOS, you need to check if VTd is enabled and if the mat is supported. board and processor is a set of instructions.
