How to disable “#enable-lookalike-url-navigation-suggestions” in Chrome

If you are using version 87.0.4280.88, the flag is not present. It was present on version 86 under another name (#use-lookalike-for-navigation-suggestions) as shown on my answer here.

If you want to it to be listed, you have first to enable #temporary-unexpire-flags-m86. Then restart Chrome.

After restarting Chrome, search for #use-lookalike-for-navigation-suggestions. It will be displayed, and you can disable it.

But note that both flags, might not be listed in future releases of the browser.

Looking online indicates this flag and feature were being developed a year ago (multiple articles from January 2020). There is no indication it has been released.

Searching Chrome on my own systems I do not see the flag either.
