Once upon a time, there was a link in the Jetpack settings to a screen that would let you manage all of the Jetpack modules in one place. The link may have been removed, but you can still access this settings screen directly.

Just add this to your site’s URL and it will take you directly to the bulk settings screen.

/wp-admin/admin.php?page=jetpack_modules

From here you can turn on/off the various modules and you can do it without any code snippets too. It helped me disable the form module since I’m using Gravity Form here. Hopefully, it’ll help you out too.
