Chat and embed code

Hi,
I’m new here and my english is not too much.
I did a good search in the forum, but I did not find help. Here is the context and my questions. I have a conference to do with Zoom that I want to re-transmit via a private platform with the Twitch embed code.
Questions:
Can I hide my streaming on the Twitch platform?
Can I completely remove the chat window from my broadcast because my private platform has its own personalized chat?
Thank you to answer me, hoping to find miracle solutions.
