So I am having major problems getting this to work

My setup is as follows

Motherboard: Supermicro X10DAi (SR-IOV enabled)
Processor: Intel Xeon E2650-V3
Memory: 128GB DDR4
GPU: Nvidia Grid K1

When I try to dismount the card from the host I get the following:
Dismount-VmHostAssignableDevice : The operation failed.
The current configuration does not allow for OS control of the PCI Express bus. Please check your
BIOS or UEFI settings.
At line:1 char:1

  • Dismount-VmHostAssignableDevice -force -locationpath $locationpath
  •   + CategoryInfo          : InvalidArgument: (:) [Dismount-VMHostAssignableDevice], Virtualizat 
 ionException
  + FullyQualifiedErrorId : InvalidParameter,Microsoft.HyperV.PowerShell.Commands.DismountVMHos 
 tAssignableDevice

Does this card support it, also what is the difference between Grid K1 and Grid vGPU K1

when i run the survey script from microsoft i get the following

NVIDIA GRID K1
BIOS kept control of PCI Express for this device. Not assignable.

Unfortunately, this machine doesn’t support using them in a VM.

To use SR-IOV on this system, the system BIOS must be updated to allow Windows to control PCI Expre
ss. Contact your system manufacturer for an update.
SR-IOV cannot be used on this system as the PCI Express hardware does not support Access Control Se
rvices (ACS) at any root port. Contact your system vendor for further information.
