Hello @Pratim Das, Partha C ,
Right now there is no automatic Sync integration between AKS and Keyvault TLS certificates.
You can find more details @ https://github.com/MicrosoftDocs/azure-docs/issues/28137
Couple of alternate options were also discussed there :-

However, using the above link, you will see that the Azure Key Vault FlexVolume for Kubernetes project enables direct integration from Kubernetes pods to KeyVault secrets.
