Take a look at this topic:

SOLVED::TinymceRte - how to remove the Fonts options?

I believe directly in the system settings you can only show/hide an entire menu item in the setting tinymcerte.menubar. If you want to remove a subitem inside the “Format” menu, you probably have to create an external config file (system setting tinymcerte.external_config) with content like this: {"menu":{"format":{"title":"Format","items":"bold italic underline"}}} This shows only the specified items “bold italic underline” in the “Format” menu. Copy the default items list from the document…

It seems the link in that response is no longer correct. So try this one:
