I don't think this can be easily done. If you want to try to reduce ping, make sure you "disconnect" all other PC's on your network. You could also disable WIFI connections and make sure your PC is connected with Ethernet cable. You can also use Razer Cortex to temporarily disable background application on your PC that might be using the internet connection. This works for me in BF1 and I have a 500KB/PS interner connection, and a ping of about 85ms.
Hope that helped.
