Sure
ZWO recommends Dark Flats or Flat Darks over bias as their sensors don't work too well with very small exposures Hence bias frames are useless and tend to stuff up the flats when combined, the best flats and dark flats for these cameras are in the average range of 25000 to 30000 adu at 2-3 second exposures for flats and the same for the flat darks (with the cap on) the flat darks are more or less bias frames better matched to the flats.
These cameras work better this way then the old CCD or dslr's
If you follow cloudy nights or the ZWO cameras facebook page it's all over it. as for scientific explanations I'll leave that to the nerds
