Where can I find a list of all available ChromeOption arguments?

This is the one I use: http://peter.sh/experiments/chromium-command-line-switches/

var options = new ChromeOptions();
options.AddArgument("--start-maximized");
options.AddArgument("--ignore-certificate-errors");
options.AddArgument("--disable-popup-blocking");
options.AddArgument("--incognito");

and so forth :)

List of common switches :
/master/chrome/common/chrome_switches.cc

List of headless switches :
/master/headless/app/headless_shell_switches.cc

To search other switches :
https://source.chromium.org/search?q=file:switches.cc&ss=chromium%2Fchromium%2Fsrc

List of preferences:
/master/chrome/common/pref_names.cc

Here is an answer about how to use the ChromeOptions used:

ChromeOptions options = new ChromeOptions();
options.addArguments("test-type");
options.addArguments("start-maximized");
options.addArguments("--window-size=1920,1080");
options.addArguments("--enable-precise-memory-info");
options.addArguments("--disable-popup-blocking");
options.addArguments("--disable-default-apps");
options.addArguments("test-type=browser");
