disable forgot password in laravel 7

1. Simple Method :  
  Auth::routes(['reset' => false]);

2. If that doesnt work, in ForgotPasswordController, you will see that a trait
    SendsPasswordResetEmails is used, in that you will find the function
    showLinkRequestForm which you can override:

    public function showLinkRequestForm()
    {
        return view('auth.passwords.email');
    }

and replace it with a redirect to go back, or a 404, or something else that you
want.
