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

[lee]

The helm chart I am using is as follows.

===
apiVersion: v1
appVersion: 1.17.1

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.

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