Ability to drop x-envoy-* headers

1

I’m trying to figure out if there’s a way to drop headers when making requests outside the cluster. I’m noticing that envoy adds some headers even if the service is not a part of the mesh. Is there a way for me to tell envoy not to do that ?

curl http://httpbin.org/headers
{
  "headers": {
    "Accept": "*/*", 
    "Content-Length": "0", 
    "Host": "httpbin.org", 
    "User-Agent": "curl/7.52.1", 
    ...
    ... 
    "X-Envoy-Attempt-Count": "...", 
    "X-Envoy-Peer-Metadata": "......", 
    "X-Envoy-Peer-Metadata-Id": "..."
  }
}
