No...............5- alpha reductase is the enzyme responsible for the conversion of testosterone to DHT not the aromatase enzyme so an AI will not lower DHT you would need a 5 alpha reductase inhibitor like finasteride or dutasteride.
Depending on your reasoning think twice before you purposely lower DHT as it also has many benefits.
If any effect, it should RAISE dht. Less T converting to e2 means more T available to convert to DHT. Not saying it actually does but in theory, it could raise DHT.
