Disabling a package

The :disabled keyword inhibits loading a package, and all its customizations. It is equivalent to commenting out or deleting the definition.

You could use this, for example, to temporarily disable a package that you’re having difficulties with, or to avoid loading a package that you’re not currently using.

This example disables the ‘foo’ package:

(use-package foo
  :disabled)

When byte-compiling your init file, use-package omits disabled declarations from the output entirely, in order to make Emacs startup faster.
