Then, we can give disabling welcome screen on chrome with below.

--disable-fre

• https://chromium.googlesource.com/chromium/src/+/master/chrome/test/chromedriver/chrome_launcher.cc#100

"chromeOptions": {
    "args": ["--disable-fre"]
}

BTW, we can see which capabilities are available as the chrome option in https://chromium.googlesource.com/chromium/src/+/master/chrome/test/chromedriver/capabilities.cc#541 . The args is there, but prefs is only in non Android. So, prefs is available PC chrome.
