How to restrict user to turn on Audio and Video in Jitsi conference call?

Question

I want to restrict certain user to turn on Audio and Video option in Jitsi meet activity. I am able to mute Audio and Video but user can turn them on back. I want to completely restrict them to turn them on.

Here is code snippet I have,

JitsiMeetConferenceOptions defaultOptions
                        = new JitsiMeetConferenceOptions.Builder()
                        .setServerURL(new URL(APIClass.JITSI_SERVER_URL))
                        .setWelcomePageEnabled(false)
                        .setAudioOnly(true)
                        .build();

JitsiMeet.setDefaultConferenceOptions(defaultOptions);

I found couple of methods but it is not useful as per the requirments,
