proxyProtocol support not clear

[atamgp]

I want to use apisix combined with nlb in aws + eks using proxyProtocol see here
In the values file for the master branch chart you can configure this:

{{- if or .Values.gateway.proxyProtocol.http.enabled }}
  - name: apisix-gateway-pp-http
    port: {{ .Values.gateway.proxyProtocol.http.servicePort }}
    targetPort: {{ .Values.gateway.proxyProtocol.http.containerPort }}

url

But this port is not used in the pod template of the same master branch, so only on the service but missing on the pod...

In the latest chart 2.4.0, proxyProtocol is completely missing:

Please explain how to configure proxyProtocol.
