Como faço para desativar a opção de fixar/desfixar para meus usuários do fórum?

Unpin Restrictions

Is there any way to prevent regular users from unpinning topics? I’m well aware that many forums abuse the usage of pins, which is probably why Discourse allows members to unpin, but I only wish to pin the most important information and I want that to remain pinned until a moderator or admin unpins it.

What is the problem you are trying to solve by preventing users from unpinning posts?
