Disable emails in OJS 3.101

Some of the standard emails are greyed out so they cannot be disabled. Is this as it should be? I would have thought with Admin access I should be able to change any of the email settings?

Yes, for those which are greyed you can enable that via phpmyadmin. If you are familiar with phpmyadmin I will show you how to do that.
You can tell to your administrator to do the following:
choose table mail_templates_default and in column can disable enter 1 instead of 0 for Notification. See image below:
Itwill not be greyed anymore so you can disable it according to instructions in previous post.
