Late Ali Khamenei issued a religious decree and declared nukes impermissible. The basis for that decree makes sense to some extent if you consider the mass destruction and harm it could bring to innocent civilian population.
Did he ever say or mention anything about closure of strait of Hormuz?
Because if you look at it, the end result is basically same (obviously on drastically varied scales but in religious terms a harm to civilian population is a harm).
Hasn't iran nullified his decree already in a way?
