How to disable supplier contact user account creation email or notification

Summary

Requirement is to not send the Supplier Contact User Account creation email or notification

Content

Supplier contact receives 2 e-mails after the creation of supplier contact user account:

1. A Welcome E-mail with their Username and link to set the Password. 
2. An email with the supplier contact information including roles and a hyperlink for access to the application.

My requirement is that the supplier users should not receive this notification / Email as we customized the first welcome e-mail content and providing all the relevant information there. The second email will be duplication for the same.
