Troubleshooting AirPod Updates:
What firmware is installed? What is the model of your AirPods? Go here, and see if you have the latest: About Firmware Updates for AirPods - Apple Support. Unfortunately, your cannot push AirPod updates. So, pair these to a device that is already connected to the Internet, and they will be updated automatically, sure enough.
