Yes, the system is CNVio2 compliant (it has an 11th generation CPU, while CNVio2 requires 10th gen and up).  
I just upgraded my WiFi to 6E and would like to replace the AX1650 card in my XPS 9710 with an AX1690i card, which is a CNVio2 card.  Is the XPS 9710 fully CNVio2 compatible or do I need a straight PCIe card? Thanks
XPS 9710, AX1690i WiFi card, compatible?
