Disable JavaScript when running Cucumber tests

Question

I am using Capybara and Cucumber to run some integration tests, one of which requires JavaScript to be disabled, I can achieve this manually by going to developer tools and disabling JS (Chrome), but how can I automate this process. I would like an option to start a browser up with JS disabled or enable/disable mid test

Capybara.register_driver :chrome do |app|
  chrome_binary = ENV["HENDRICKS_CHROME_BINARY"]

  if chrome_binary.nil?
    Capybara::Selenium::Driver.new(app, :browser => :chrome)
  else
    capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
      "chromeOptions" => {
        "binary" => chrome_binary + "/Contents/MacOS/Chromium"
      }
    )
    Capybara::Selenium::Driver.new(app, :browser => :chrome, :desired_capabilities => capabilities)
  end
end

Is this possible with Chrome as my browser?

Why is it when you post a question you figure it out minutes later.. For anyone interested this is what I have done to disable JS

Capybara.register_driver :js_disabled do |app|
  chrome_binary = ENV["HENDRICKS_CHROME_BINARY"]

  if chrome_binary.nil?
    Capybara::Selenium::Driver.new(app, :browser => :chrome)
  else
    capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
      "chromeOptions" => {
        "prefs" => {
          'profile.managed_default_content_settings.javascript' => 2
        },
        "binary" => chrome_binary + "/Contents/MacOS/Chromium"
       }
    )
    Capybara::Selenium::Driver.new(app, :browser => :chrome, :desired_capabilities => capabilities)
  end
end

Note the prefs object passed via the chromeOptions
