Sorry, but I did not realize how the kube-proxy custom parameters are reflected in kube-proxy configMap

Sorry, but I did not realize how the kube-proxy custom parameters are reflected in kube-proxy configMap

They are passed as KubeProxyConfiguration to kubeadm init using kubernetes.get_kubeadm_config() https://github.com/Netcracker/KubeMarine/pull/571/files#diff-06f6e567fbbc6e8f10df941795f81ed273577ac92778a9e67c6b52be1a65fbbe

kubeadm will manage itself how to fill kube-proxy configMap

So, what is the way to change kube-proxy configuration after the installation procedure?

No way, as much as there is no way to change any custom configuration managed by kubeadm after the installation procedure.
