Hi, there is no such option at this time.  
In case you’re a developer, check this: [Support Avoid Areas for Matrix Requests by Nakaner · Pull Request #801 · GIScience/openrouteservice · GitHub](https://github.com/GIScience/openrouteservice/pull/801) It is untested though and not implemented, you would need to configure this yourself.
