There is no method to restrict the use of Incognito Mode for Google chrome on iPhone. If you want that no one uses your phone for Incognito, you can do so using Safari. If you don’t know how to disable incognito mode on iphone, then first of all you need to open settings on iOS device, and then tap General. Next, tap Screen time and then Restrictions. Also, if you are using an older version of iOS, you can go to the Restrictions directly from General Menu. Now, enable Restrictions and enable a pass code so that no one lifts the instructions other than you.
