My mistake, it is not the Areion, it is the ROG 10g Express that uses the Tehuti TN9510 chipset, here is what is being detected on my setup (it shows in both Unraid and Windows 10 as being Tehuti):
IOMMU group 13:[1fc9:4025] 04:00.0 Ethernet controller: Tehuti Networks Ltd. TN9510 10GBase-T/NBASE-T Ethernet Adapter
01:00.0 Ethernet controller [0200]: Tehuti Networks Ltd. TN9510 10GBase-T/NBASE-T Ethernet Adapter [1fc9:4025]
