Istio nodeagent

Hi All, We are using istio in EKS.
We have disabled nodeagent and it is working fine. Is istio nodeagent a compulsory for citadel?
is nodeagent only for onprime

Node Agent is not required for Citadel. Node Agent is only required when you want to use SDS

Node Agent should work on any k8s platforms (GKE, EKS, etc.)
