verificationOfPayee.bulkPayments controls Verification of Payee on SEPA payments submitted in a bulk of two or more payments:

• Opting out requires a stepped-up session, and the user must have been shown the risks of opting out beforehand. Opting out is only available once the embedder's opt-out screen has been certified.
• Opting back in is always possible and needs no step-up.

Payments submitted on their own always go through Verification of Payee.
