In istiod installed via helm, meshConfig options do not take effect

The helm chart I am using is as follows.

apiVersion: v1
appVersion: 1.17.1
description: Helm chart for istio control plane

I set accesslog and discovery selectors through the meshConfig option of values.yaml, but the settings are not applied. Please give me your opinion on which point should I troubleshoot.


accessLogFile: /dev/stdout
accessLogEncoding: JSON
discoverySelectors: true
