Disabled New User Profiles Emails

Can anyone please enlighten me how to disable New User Profiles emails from being sent?

My site is being flooded by fake user registrations. Their fake email addresses cause high bounce rate which lead to my SMTP service account suspension.

1 VARIANT. Open the app/controllers/frontend/profiles.php file and replace

$res = fn_update_user($auth['user_id'], $_REQUEST['user_data'], $auth, !empty($_REQUEST['ship_to_another']), true);

with

$res = fn_update_user($auth['user_id'], $_REQUEST['user_data'], $auth, !empty($_REQUEST['ship_to_another']), false);

2 VARIANT. Use the update_user_pre hook (app/functions/fn.users.php) to change $notify_user to false for new registrations in the store-front
