As i read Driverkit can be used to write the device driver. But, I want to filter a device. can Driverkit be used for filtering a particular device?

On MACOS Catalina, I have written the Transparent App Proxy and am able to redirect the flow to my application. That application in turn opens the flow to remote server . I want to avoid any processing on the traffic coming from this application which is connecting to same port as the original client application and hence falling into same rule and landing back in my handleNewFlow . I am not sure how to ignore these flows originating from my own application . since returning NO from handleNewFlow closes that connection . this appears to be a common problem with any proxy application . any pointers, API or mechanism which will help me ?
