disable passwd access to spice and specify disable-ticketing

Hi! i need to have passwordless auth to spice (because it is restricted to 127.0.0.1 and nobody can connect to it, in feature i want to use it via unix socket). I'm checking docs at libvirt site and don't see any disable-ticketing options. SO how can I pass this option and allow access without a password to spice?
