Not possible Change name via command and notification question

Hello,
I was wondering if it is possible to change name on a TS3 server using commands but only as a user.
This is because I have created a music bot and would like to make it change nickname whenever a song changes to reflect the name of the song.

Also, is it possible to mute all notification sound of only a particular user? For example, let's imagine I had a friend that kept on posting stuff that didn't interest me and I didn't want to hear the notification sound whenever he wrote something in the TS chat, however I still wanted to hear it when someone else wrote something.

Thanks for any help you may provide.

Take care.
