fzero doesn't use the iteration count variables in the options object, true.
If it were important-enough to you, you could write an output function and have it count the times it was called and return the stop flag variable as true when a desired number of iterations reached. The internal counter would have to be made persistent, of course, to retain the count between calls.
I've never tried such a thing but seems at least theoretically possible altho begs the question of "why?" would you need it...
