Is it possible to completely disable trust levels?

I’m new here and just set up my forum. It is to be a smaller, invite only working group. I understand the logic behind the trust system but there are reasons some people would prefer not to use it. With our group we don’t want badges or hierarchies and we’re not really into gamification and behaviorism. However, I realize that if I were trying to create a large community open to all this becomes more difficult. Discourse looks amazing though. I’m looking forward to using it!
