title: Has mongoid replacement for rails save(touch: false)
body: <p>Ruby on Rails active_record has option {touch: false}, when record is saved to database, since version 5. <a href="https://blog.bigbinary.com/2016/05/09/rails-5-allows-updating-without-updating-timestamps.html" rel="nofollow noreferrer">https://blog.bigbinary.com/2016/05/09/rails-5-allows-updating-without-updating-timestamps.html</a></p>
  <p>I can not find if this (or similar) option is implemented in mongoid too. {touch: false} doesn't seem to work.</p>
