How to disable chat on the live page of VKontakte so as to disable message traffic?

Question

JavaScript

Broadcasts where a lot of (10000+) spammers gather lag due to the fact that my 4Mbps is not enough for both video and chat messages. Support said that with such a speed I won’t be able to see anything at all, but with an adequate number of messages, everything is fine.
Hiding the element, as I understand it, will not solve the problem. It is necessary to edit the scripts somehow dynamically.
Or did the VK team simply not bother with video compression?
Do not offer to buy more speed for the sake of one VK :)
