Selenium webdriver: Modifying navigator.webdriver flag to prevent selenium detection

Question

I\'m trying to automate a very basic task in a website using selenium and chrome but somehow the website detects when chrome is driven by selenium and blocks every request.

Nowadays you can accomplish this with cdp command:

driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
  "source": """
    Object.defineProperty(navigator, 'webdriver', {
      get: () => undefined
    })
  """
})

driver.get(some_url)

by the way, you want to return undefined, false is a dead giveaway.
