You should be able to switch on "Ethernet Backhaul Mode" and that will release the 2nd 5GHz radio.
See the attachment. That's from a GT-AC5300.
I was able to add the second 5GHz radio to Smart Connect and this is the single most important addition 386 adds for me.
Try to find if that is an option on your Lyra.
And be aware this is causing big troubles for people using a dumb switch in between router and node - most likely because of lack of support for large MTU.
I'm not assuming the Lyra to get 386 and AiMesh 2.0, so I went ahead and ordered a 2-pack of AX92U.
i was under the impression that the "switch" issue was resolved in the most recent firmware: 1. Fixed Ethernet backhaul through switch issue
But I was planning o hook them up directly anyway
