Intel X710 10GbE SFP+ (passthrough) not detected

Hello,

I have a Minisforum MS-01 which have two Intel 2.5GbE and two Intel x710 SFP+.

I'm using Proxmox and I did a PCIe passthrough of one x710 interface (tick/untick pass all feature doesn't matter) to Sophos XG v20 Virtual Machine. By doing an lspci, the PCI device is detected as 8086:1572 but Sophos is not loading the i40e kernel driver:

The i40e driver seems to be the right by looking at it with strings command:

There is a way to force the load of this kernel module? (insmod command is not there)

Thank you,

Daniele
