Cannot apply networking - disableDefaultCNI: true option in kind.sh

First of all, thanks for providing this awesome samples for hlf.
What I want to do is securing hlf network on k8s by cilium.
I expect that applying network policy in in the network might block some dangerous actions such like DeleteAsset when API_KEY is exposed.
To do that, in my knowledge, I need to apply
```sh
#/test-k8s-network/scripts/kind.sh#130
networking:
disableDefaultCNI: true
```
However, when I apply this option, there is no progress after
```
- waiting for cert-manager
```
Is there any suggestion for this? I would appreciate if you advise for me.
