How to hide Library in whiteboard?

Is there a possibility to hide Library on the whiteboard?

[yasmagic]

Any idea how to hide the Library tool?

You can remove the preload Libraries in this section of config.js file:
window.WHITEBOARD_PRELOADED_LIBRARY_ITEMS = [];

Don't know about the key itself, it's provided by the whiteboard (Excalidraw) itself.
