Faster way to restart static pods after configuraiton changes

In the past several days, I practiced several exercises for my coming CKS exam. I noticed that it takes a while to get static pods restart after configuraiton changes. I was curious if there is any faster way to make that happen. I think the following ways definitely will be faster than waiting 3 minutes after I used them for a while. The observable time is shorter than 3 minutes

Delete pods

# add workernode
 crictl ps --label  io.kubernetes.pod.name=kube-apiserver-kind-control-plane
 #assume pod id: facc8f153d9d2
 crictl stopp facc8f153d9d2
 crictl rmp facc8f153d9d2

#controlplane
kubectl -n kube-system delete pod kube-apiserver-kind-control-plane --force --grace-period=0

restart kubelet

systemctl restart kubelet

kubelet
pods
