Due to the security context(runAsNonRoot) container cannot run successfully

CLI versions

cf-for-k8s: v4.2.0
cf version: 7.2.0+be4a5ce2b.2020-12-10
kubernetes version: v1.19.8

Describe the bug

After I deployed cf-for-k8s, I try to push one nginx docker container to cloud foundry using cf v7 client.

cf push nginx --docker-image nginx:latest

But the pod status is "CreateContainerConfigError"

$ kubectl get pods -n cf-workloads
NAME                                                    READY   STATUS                       RESTARTS   AGE
nginx-processing-pipeline-bc88a52a07-0                  1/2     CreateContainerConfigError   0          22s

Then I describe pod, found below events show that "container has runAsNonRoot and image will run as root"

kubectl describe pods nginx-processing-pipeline-bc88a52a07-0 -n cf-workloads

...

Additional context

If I change the "securityContext.runAsNonRoot" from true to false, this pod will run successfully

kubectl get sts nginx-processing-pipeline-bc88a52a07 -o yaml

apiVersion: apps/v1
kind: StatefulSet
metadata:
...
spec:
...
    spec:
...
      securityContext:
        runAsNonRoot: true  -> false
      serviceAccount: eirini
      serviceAccountName: eirini
      terminationGracePeriodSeconds: 30
...

Expected behavior

How can I change the default StatefulSet template to disable runAsNonRoot? Is there a parameter that controls the securityContext? Or I can change something in the rendered YAML file "cf-for-k8s-rendered.yml"?
