Hi,
The combo-group creates an "port backup".
This is example on Aruba 5500:
How to see it on NAV ?

I have no idea, having no experience with Arista. What is a "combo group"? Is an LACP aggregate?
On the manual:
On a HP 7500 switch, a combo interface is a logical interface that comprises one SFP fiber port and one RJ-45 copper Ethernet port, which are called combo ports. The two ports share one forwarding interface and cannot work simultaneously. When you enable the RJ-45 port, the SFP port is automatically disabled and placed in the inactive state, and vice versa. By default, the port with a smaller number is active. You can use the display port combo command to identify the combo interfaces on the switch and the active status of their member ports.
Same on HP 5500.
I suspect that is not configurable, because the both port number are printed on SPF port:

Then I would expect the logical interface to have its own entry and name in the interface table, and I would expect the layering of the logical interface on top of the physical ones to be described in the `IF-MIB::ifStackTable`.
For NAV, this means the logical interface should be listed separately, and when view its port details in ipdevinfo, there should be a "Layering" table that lists the two physical interfaces on the lower layer.
I cannot confirm that this actually works on HP devices, as I don't have access to any that use port combos.
