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

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. I suspect that the website is relying on an exposed DOM variable like this one https://stackoverflow.com/a/41904453/648236 to detect selenium driven browser.

My question is, is there a way I can make the navigator.webdriver flag false? I am willing to go so far as to try and recompile the selenium source after making modifications, but I cannot seem to find the NavigatorAutomationInformation source anywhere in the repository https://github.com/SeleniumHQ/selenium

Any help is much appreciated

P.S: I also tried the following from https://w3c.github.io/webdriver/#interface

Object.defineProperty(navigator, 'webdriver', {
    get: () => false,
  });

But it only updates the property after the initial page load. I think the site detects the variable before my script is executed.
