Yes, it’s possible. You should go through to the available methods in [plugin/instance.rb](https://github.com/discourse/discourse/blob/master/lib/plugin/instance.rb) file. You can also check existing plugin codes to learn about how they handling different situations. And go through [Developing Discourse Plugins - Part 1 - Create a basic plugin](https://meta.discourse.org/t/beginners-guide-to-creating-discourse-plugins-part-1/30515).
