It is easy to connect first device to IoT Central. There is step by step. By I want to connect second Azure Sphere device to IoT Central. It is added automatically, just because it is in Azure Sphere Tenant.

But I need to add generate Leaf Certificate for that device. How to do it step by step?

The way to use a Device Provisioning Service (DPS) to connect devices to an IoT Central application is documented here: https://docs.microsoft.com/en-us/azure-sphere/app-development/setup-iot-central. This will allow you to connect millions of devices to your application and all the devices can use the same application build.

The Avnet OOB examples use connection strings and are not setup to use DPS. You can look at the Microsoft examples on GitHub which all use DPS (I'm pretty sure).

If you are using the Avnet OOB examples, you can just manually create a second device and connection string, like you did with the first device. This will require that both devices use different application builds, each with the correct connection string.
