No, there isn’t a way to remove them, because they’re part of the internal logging mechanism and the info is useful for solving issues; you’ll appreciate their purpose when you go through this guide (link).
Now, I understand that you’re just looking to simplify the existing logs, so, this is not the solution (it’s called Event Manager) you’re looking for. However, I have found this immensely useful, when I had to automate the monitoring of Events and trigger desired actions.
Take a look at this brief post (link) and refer Chapter 43 (page 909) in the Service Development Help, here (link).
