Disable CSS and JS from a contributed module I am using Simple Mega Menu module.

I want to disable the CSS and JS provided by this contributed module:


modules/contrib/simple_megamenu/js/simple_megamenu.js
modules/contrib/simple_megamenu/css/style.css


In the module description the say 


  Simple Mega Menu provide basic styling. You can override the library
  (css/js) provided by this module simply by adding theses lines into
  your theme file my_theme.info.yml


libraries-override:
  # Replace an entire library.
  simple_megamenu/base: my_theme/megamenu


How do I disable the CSS and JS files properly in my_theme.info.yml?
I think setting the library to FALSE should work:

libraries-override:
  # Replace an entire library.
  simple_megamenu/base: false
