Can you disable all members from deleting their forum replies?

At the moment if you create a reply to a forum post, as a member, you are always able to delete your own reply. In some cases if that reply has nested replies, you will even be able to delete the child replies to it.
Basically deleting other member's content.

There is a way to disable editing and deleting original forum threads but is there also a setting somewhere to disable this for replies?
