I'm pretty sure that I'm not the first, and pretty danged sure that I'm not going to be the last person to ask this question, but I would like to ask: Is it possible? According to all the threads I've found so far regarding this case, all info points towards that of a "Yes, but not possible at this moment of time". One thing I've gathered about it is that apparently finding and/or the exact place the update is saved to is a main issue. The rest of the aforementioned threads only gave prevention as an answer. Furthermore, the method to delete update data from sysnand apparently doesn't work either in the case of emunand, so I'm quite in a pickle.
