I tried that, got some distance, but in the end *I* couldn't get the GUI to work via the Armbian config tool (not with the hotplug override workaround for vncserver). On another note, I also tried with a stock Debian-buster, but ended up eventually with a corrupted sd card (??).
Went back to the 'proper' armbian-for-orange-pi zero, and although *I* can't get auto-login to work still, I've managed to workaround it with node-red. node-red's systemctl enable works, even without the user login, and upon startup, I've got node-red executing the 'vncserver' command line to start the vncserver....
no another topic awaits me - how to connect tightvnc to my realvnc cloud? (another thread somewhere I'm sure.....)
