Using certificates and secrets stored in Azure Key Vault using the Secrets Store CSI driver in Azure Kubernetes Service (AKS)

Dear Istio Community
We are using Azure Kubernetes Service for our container-based app. We are storing all our certificates and secrets in Azure Key Vault. We are also using Istio Service Mesh in our current architecture. We want to integrate between Istio Ingress Gateway to Azure Key Vault so that we can refer to the 3rd party certificate stored in Azure Key Vault. We are also using the Secrets Store CSI driver in our current architecture. I already read “Integrate between Istio Ingress Gateway and Azure Key Vault to use stored certificates and secrets”. This article seems to be a custom solution for the new installations, but we want to perform this integration with our existing installation without reinstalling Istio. What I want to know is whether Istio has a supported native solution with the CSI driver for this integration.
Kind Regards,
