##### Kube Proxy Replacement
[Kube Proxy Replacement](https://docs.cilium.io/en/latest/network/kubernetes/kubeproxy-free/) is supported through this method. The is a prerequisite for Gateway API Support.
##### Gateway API Support
[Gateway API Support](https://docs.cilium.io/en/latest/network/servicemesh/gateway-api/gateway-api/#gs-gateway-api). This will install additional CRDs to support GatewayAPI.
##### Hubble Observability
In addition to setting up [Setting up Hubble Observability](https://docs.cilium.io/en/stable/gettingstarted/hubble_setup/#hubble-setup), you may choose to install the hubble client with `kubernetes_cilium_hubble_client: true`
