Is there a way to set a default value if the secret is not present in the Key Vault?

If this is possible then can someone let me know how?

We have a scenario where we have new secrets being created and would like to make the "optional" and not cause the pod to fail on creation.

From what I have read, the secret must exist in the Key Vault and if they are not present the container will fail to start.

It's not optional. All the secrets defined in the SecretProviderClass need to exist in the keyvault. If the mount fails, kubelet will retry the volume mount until it succeeds.
