Yes! As long as you have selected Apple Music & iTunes on the DSPs page when you add your release, your music will be registered with Shazam automatically.
If you added your release before August 2023, we delivered your tracks to Shazam if you opted in to Shazam on the Optional Extras page of adding a release. As Shazam registration happens automatically when we deliver releases to Apple Music & iTunes, it no longer displays on the Optional Extras page.
