Binning is definitely a possibility. Separately from binning, there are often just features that don't work right and get disabled with "chicken switches" or "feature enable bits."

Any two-ANE design would have a lot of control logic that has to be right, e.g., to manage which work gets sent to which ANE, which cache lines get loaded, etc. It's easy to imagine bugs in this logic which would only show up when both ANEs are enabled. So it's likely that there is a chicken bit that you could use to disable one of the ANEs and run in single-ANE mode.
