https://www.armbian.com/nanopi-neo/ -- 'problem' solved.

Schematics are available, the link above (hardware solution) describes this pin in detail and if it wouldn't be defined in the fex file Wi-Fi wouldn't work at all. Since I still don't understand what you're asking for I'll stop. It should be clear where to tweak what to test whatever you want with Wi-Fi

Huh? Ethernet isn't disabled by default and Wi-Fi can be disabled -- see post #37 in original thread (also remove the xradio... occurences from /etc/modules to prevent warnings in dmesg output)

Wi-Fi isn't active until the driver is loaded. So by removing stuff from /etc/modules you ensure that Wi-Fi is disabled. The above command just ensures that the Wi-Fi chip is cut off from power. A hardware 'solution' is possible too: https://forum.armbian.com/index.php/topic/759-tutorial-i2s-on-orange-pi-h3/page-2

It's off by default: https://github.com/igorpecovnik/lib/blob/master/config/fex/orangepizero.fex#L566 -- so why don't you simply follow the advise to edit /etc/modules and are happy having disabled Wi-Fi then?
