How do I turn off double-opt-in for SQL contact forms?

New enterprise ZohoOne customer here.

We're trying to get ramped up in a migration (it's still failing) from Hubspot, and am now working on replicating Hubspot's Contact --> workflow in Marketing Hub.

Except - marketing hub acts like it's a newsletter publisher???

How do I turn off the double-opt-in for SQL contact request forms? I need to put these into a journey with scoring/qualification, but the double-opt-in is non-standard for an SQL form. In fact, it's stupid.

How do I turn it off?
