Removing avatars, display names, and boxes containing them?

Is there a way to remove these using only script commands and without hosting my own jitsi meet?

If they are removable without hosting my own jitsi meet, would removing them remove the mute everyone and kick out options that appear above them?

I’m using the api with configOverwrite: {startAudioOnly: true, to prevent video at and, as others, would like to remove the ability of people to kick others out and to mute others.
