tl;dr: Put your Zero2 and/or any other H616 based device on the shelf and WAIT for proper support to come. And no. There is no ETA. Assuming usable state end 2021/beginning 2022.
Software support is still work in progress and under heavy development. Provided preview images can break any time. Do not report this, we are aware of that and can/will not help you with that if you are not willing to investigate and research by yours
I tried to enable onwire both with stable, edge and factory images, but none worked using overlays. So it seems we are not there yet.
