title: Rubocop disable rule in AllCops
body: <p>I'm trying to disable a rule defined in AllCops - it appears that</p>
  
  <p><code># rubocop:disable all</code></p>
  
  <p>does not ignore rules defined under AllCops, specifically TargetRubyVersion.</p>
  
  <p>Is there a way to completely disable Rubocop altogether for a certain block of code?</p>
