It should be possible, but there is a bug in the code. You may want to
open a ticket. The problem is that the bit_rate is never passed to the
encoding function, leading to all DNxHD formats to fail. The value in
avctx->bit_rate is bogus.
I looked at fixing it, but the function is not trivial. I will try
tomorrow with a more fresh mind.
