I do not have the option on my phone to turn the sound off on my case for the Air pod pros 2nd gen.

Hello Kgolden3589,

Welcome to Apple Support Communities. It looks like you are on the right track following the guidance in Change settings for AirPods Pro (all generations). Since the option to enable or disable charging case sounds, try restarting your iPhone and resetting your AirPods which may refresh the connection. If needed, reference restart your iPhone. Follow this guidance from How to reset your AirPods and AirPods Pro.

"How to reset your AirPods and AirPods Pro

You might need to reset your AirPods if they won't charge, or to fix a different issue.

1. Put your AirPods in their charging case, and close the lid.
2. Wait 30 seconds.
3. Open the lid of your charging case, and put your AirPods in your ears.
4. Go to Settings > Bluetooth. Or go to Settings > [your AirPods].

• If your AirPods appear there as connected, tap the More Info button  next to your AirPods, tap Forget This Device, then tap again to confirm.
• If your AirPods don't appear there, continue to the next step. 

5. Put your AirPods in their charging case, and keep the lid open. 

6. Press and hold the setup button on the back of the case for about 15 seconds, until the status light on the front of the case flashes amber, then white.

7. Reconnect your AirPods: With your AirPods in their charging case and the lid open, place your AirPods close to your iPhone or iPad. Follow the steps on your device's screen."

Take care.
