Bulk change of default selection of activity notification emails

Hello,

by default ownCloud informs user per email on shared folders through the activity app. Is there a way to disable this for all users in a bulk editing? Or can I do some presetting so that new users have all emails from the activity app unchecked?

Thank you!

Hi im looking for this solution as well, but i didnt found anything , have any suggested action for this ?

Thanks!
