[qutebrowser] Is any way to disable WebRTC ?

[Гена Г via qutebrowser]

Hello.
 
I use your qutebrowser via proxy.
I set:
...
sys.argv.append('--qt-arg')
sys.argv.append('content.webrtc_ip_handling_policy')
sys.argv.append('disable-non-proxied-udp')
...
This is not working via proxy (socks or http) . Real public IP transfered via 
STUN .
 
Is any other way to disable WebRTC or make fake IP ?
 
Thanks.
