We can disable CVV checking in Luminate Online with the site option below so transactions that fail CVV matching will still go to the payment gateway for approval.

PAYMENT_VOID_CVV2MISMATCH:

(TRUE/FALSE) This flag is necessary when the payment processor does not reject transactions that fail CVV2 checks. When set to TRUE, it will VOID an approved transaction that fails CVV2 check. This flag is only effective when PAYMENT_CARD_VERIFICATION is set to TRUE.

To change this site option please contact support or submit a case through the support portal to disable.
