MethodNotAllowedHttpException Path Without CSRF

I pass a route in laravel which is called by a function in JS and I have no control of it because it is external, this route is a post method since I need it to be that way but it generates me a MethodNotAllowedHttpException as I do to exclude certain routes of this validation.

Note: I have already tried adding it in VerifyCsrfToken in its exception vector, modifying that class file VerifyCsrfToken extends Middleware to a new file called class VerifyCsrfToken extends BaseVerifier with all its dependencies and I have also disabled the validations in the Middleware but none of them works for me

From the docs:

You should place these kinds of routes outside of the web middleware group that the RouteServiceProvider applies to all routes in the routes/web.php file. However, you may also exclude the routes by adding their URIs to the $except property of the VerifyCsrfToken middleware:

protected $except = [
    'your/route/*',
];
