(Optional) Module Version

No response

Description

In the Redis AVM, it is mandatory to specify the shardCount as it has a minValue of 1. This forces the user to enable clustering when creating a Premium cache, whereas in the Azure Portal, it is possible to deploy a Premium cache without enabling it. My recommendation is to make the parameter nullable so that it is not passed during deployment, allowing the deployment of a non-clustered cache.
