How can prevent Login after Register, outside of laravel vendor files?

Question

I want to prevent login after registration & I know its very easy & simple. By commenting single line we can do that. But my concern is I don't want to do this in Vendor's file.

    public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

        // $this->guard()->login($user);

        return $this->registered($request, $user)
            ?: redirect($this->redirectPath());
    }
