No, current there is no OTP support in flashrom and no patch available.
It would not be too hard to add it though... I just had no time yet.
SPIPGM (the original DOS program for the rayer programmer) apparently
got support for reading the unique IDs of winbond chips lately. Maybe
that is enough for your purposes. You can find it here:

I was wondering for a long time when/if the OTP zones would be used.
Did you encounter them "in the wild" in some product?
