How do I remove an AP from NCC without access to that NCC?

After tinkering with it for a while I find that no internet access (only a laptop and a cross-over cable to the PoE injector) and letting it time out after some time longer than 15 or 20 minutes, I am able to log in to the UI and disable NCC and configure stand-alone mode. Is there a documented procedure for this anywhere?

The recipe seems to be; "Connect both the AP and a laptop (with WiFi OFF) to a small gigabit-capable switch (the PoE++ injector won't talk 100Mbps or less evidently), no internet connectivity, no DHCP, set your laptops Ethernet interface to 192.168.1.1/24, reset the WAX650S with a paperclip or jewelers screwdriver, hold the reset button for at least 30 seconds, release, allow the AP to boot, let it fail on DHCP, DNS, NCC discovery, and everything else in the universe (So I'm waiting about 30 minutes sometimes just because I forget about it.), then point a browser at 192.168.1.2 using only http. (Eventually you may get an https redirect but I don't remember the order of execution there.) Log in to the web UI using the admin/1234 user/auth pair, then immediately set NCC Discovery to "Off". Configure the rest of the AP to your liking, then reboot one more time and check your work." That procedure has worked fine for me on 2 of the WAX650S'es and I'll try it on a couple more in a week or two. While I understand the methodology behind their IOS-like CLI, SSH-ing into the AP to copy the default config to a startup config doesn't seem to work well in this situation. — These APs are absolutely bloody fantastic in my book. "Finesse versus Brute Force" kind of fantastic. Zyxel has some really exciting silicon coming out now in their WiFi6 and WiFi7 APs and the XS1930 line of switches and you can quote me on that as a network and systems engineer of 35 years. If you have problems with this recipe please feel free to ping me back. I'll be happy to help you work it out.

Where can I contact you with pictures of the 6 APs labels to have them removed from NCC? The recipe above seems to work consistently for me, whether that's a bug in the firmware or a feature, and I currently have no need for anything other than stand-alone mode, but if I gift one or two to a friend or family I suppose I should take the necessary steps to not confuse them in the future.
