Mink and Behat: Is there a way to launch selenium (Chrome) in background?

Question

When running tests, I would like not to be bothered by Chrome popping-up every time Behat launches a scenario needing Chrome.

I know there is a maximizeWindow() method for session objects, but nothing like "minimize".

Nowadays, you can set Chrome to run in headless mode like so (behat.yml):

default:
    extensions:
        Behat\MinkExtension:
            javascript_session: browser
            sessions:
                browser:
                    selenium2:
                        browser: chrome
                        capabilities:
                            chrome:
                                switches:
                                    - "--headless"
