There's a flag to the controller manager that is in charge of retention policy for terminated or completed pods.
https://kubernetes.io/docs/reference/command-line-tools-reference/kube-controller-manager/#options --terminated-pod-gc-threshold int32 Default: 12500 Number of terminated pods that can exist before the terminated pod garbage collector starts deleting terminated pods. If <= 0, the terminated pod garbage collector is disabled.
