kubelet.configuration does not pick up changes in config file

[mm-weber]

Describe the bug
On EKS the file /etc/kubernetes/kubelet/kubelet-config.json is the kubelet.configFile.
It is possible to add and change the following FeatureGates like that:

  "featureGates": {
    "RotateKubeletServerCertificate": false,
    "RotateKubeletClientCertificate": true
  },

This is getting picked up as desired:

Adding the rotateCertificates: false parameter to the config is not getting picked up though.
It does get picked up when set via KUBELET_ARGS= or KUBELET_EXTRA_ARGS= via the --rotate-parameters setting.

To Reproduce
Steps to reproduce the behavior:

1. Create EKS cluster
2. Connect to node via cnspec shell ssh
3. Modify /etc/kubernetes/kubelet/kubelet-config.json as described
4. Note the error

Expected behavior
The parameter should be picked up.

Desktop (please complete the following information):

os 11.3.30
