GitLab Per Project Email Settings

I was wondering if there was a way to turn any and all notification for a specific project and only that project, other than globally shutting email off.

We have a client who has a, “no email” requirement and we want to be able to shut it off for only that project. If I shutoff smtp globally, then I will be unable to create accounts, unless there is a way to create an account and communicate the password out-of-band.

Any thoughts or links to resolution in this forum?
