nterfaces with an actual description are returned as a string, for example the interface with Device1ILO
However the interfaces without a description configured, are returned as Hex-STRING 00.
How can I get it to return either an empty string or a "0" when using the metrics exported to my snmp-exporter prometheus instance? I would rather not configure a description for the interfaces that are unused because there are far too many at the moment.

iso.184.108.40.206.220.127.116.11.1.18. = STRING: "Device1ILO" iso.18.104.22.168.22.214.171.124.1.18. = Hex-STRING: 00 00
