How to prevent Dialpad from creating local contacts automatically when placing a call through the CTI

When integrating with the CTI, whenever an employee makes a call through the CTI to a new contact, it creates a local contact automatically. I want to know if there's a way to prevent this behavior by default.

The main problem with the aforementioned workflow is that whenever a local contact is created, and then a shared contact is created with the same number, all call events consumed from the call event webhook show the data of that local contact, not the shared contact that was created manually.

Thank you
