How to disable ALL chrome extensions using chromedriver

After upgrading to chromedriver 74 noticed odd extensions behaviour on Windows. Is it possible to switch ALL extensions off?

  1. Start chromedriver
chromedriver --log-level=ALL
  1. Create session with extensions DISABLED
curl -d '{"desiredCapabilities":{"browserName":"chrome","goog:chromeOptions":{"args":["--disable-extensions"]}}}' http://localhost:9515/session

Some dev tool extension is loaded

[1558606783.990][INFO]: Launching chrome: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-extensions --disable-extensions-except="C:\Users\user\AppData\Local\Temp\scoped_dir19964_411\internal" --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-blink-features=ShadowDOMV0 --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --no-first-run --password-store=basic --remote-debugging-port=0 --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\user\AppData\Local\Temp\scoped_dir19964_22650" data:,

Note

--disable-extensions-except="C:\Users\user\AppData\Local\Temp\scoped_dir19964_411\internal"

Is there a way to get rid of it? Did not find any clues in chromedriver docs, those are extremely sketchy.

TL;DR

Set chromeOptions.useAutomationExtension to false, it will prevent injecting of Chrome Automation Extension

{
  "desiredCapabilities": {
    "browserName": "chrome",
    "goog:chromeOptions": {
      "useAutomationExtension": false,
      "args": [
        "--disable-extensions"
      ]
    }
  }
}

Long version

Automation Extension flag is not mentioned in chromedriver docs http://chromedriver.chromium.org/capabilities, but can be traced in source code for current version (75.0.)

    parser_map["useAutomationExtension"] =
        base::Bind(&ParseBoolean, &capabilities->use_automation_extension);

    status = internal::ProcessExtensions(
        capabilities.extensions, extension_dir->GetPath(),
        capabilities.use_automation_extension, &switches, extension_bg_pages);

  if (include_automation_extension) {
    ...
    if (switches->HasSwitch("disable-extensions")) {
      UpdateExtensionSwitch(switches, "disable-extensions-except",
                            automation_extension.value());

As mentioned in 54594305 Java code using selenium driver would be

ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
