title: Avoid smartcards using puppeteer
body: <p>When I run unit tests with puppeteer, my smartcard (observed with a YubiKey or Nitrokey) gets accessed; you can see the light blink. I am using that smart card in my host system, but do not want to access it from puppeteer.</p>
  
  <p>This slows down the tests, and is not desirable in general; the tests should certainly not use my smartcard.</p>
  
  <p>How can I prevent puppeteer/chromium from accessing smartcards? I am fine with a Linux-only solution.</p>
