You can turn off warnings for a section of your code by setting $VERBOSE to nil. Even better is to codify this in a method. Since this method takes a block as its parameter, you can now pass it arbitrary chunks of code to execute without warnings.

def silently(&block)
  warn_level = $VERBOSE
  $VERBOSE = nil
  result = block.call
  $VERBOSE = warn_level
  result
end
 
# e.g.
silently { require 'net/https' }
