How to prevent calls to internal services from going through Istio Proxy

Hi - I am having an issue where a specific process (in this case a subversion process) has an issue where the proxy seems to break the HTTP calls to SVN. Initially I used the “false” annotation to prevent SVN from loading istio. This seems to work and if I am in a pod that is not running istio the performance is fine connecting to the subversion process. However, if I have pod that is running istio the performance is extremely slow - the HTTP requests never complete. As a workaround I want to disable the source pod from going through the Istio Proxy to reach the SVN service and backing pod. Is there an annotation or mechanism to exclude calls to a specific service from going into the istio-proxy on the pod making the call.
