The CVV will never be stored in the gateway.
We do not store the cvv, it is only used for verification purposes. If you wish to re-verify a payment method, you can provide a form via hosted fields to post only the cvv and then run a PaymentMethod update with verify_card set to true and the nonce generated from hosted fields.
