OpenWrt supported access points with 6Ghz are not yet available to my knowledge - I expect that eventually Filogic 860 / 880 devices will pop up but that may take some time.
ps: for a 'Wifi-Router' Banana Pi BPI-R4 (Filogic 880 based) is close in getting supported

No guarantee though when this will be complete, let alone how soon the Wifi part is fully supported...
