Ingress controller: enable PROXY Protocol to backend TCP connection

Help!
1

I have the PROXY Protocol working fine to a backend HTTP server:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: web-static
  annotations:
    haproxy.org/send-proxy-protocol: proxy

I also have several TCP services configured in the TCP ConfigMap:

data:
  5349: "hcce/coturn:5349"
  12525: "mail/docker-mailserver:12525"
  10465: "mail/docker-mailserver:10465"
  10587: "mail/docker-mailserver:10587"
  10993: "mail/docker-mailserver:10993"

and in the HAProxy LoadBalancer Service:

spec:
  type: LoadBalancer
  externalTrafficPolicy: Local
  ports:
    - name: coturn
      port: 5349
      protocol: TCP
      targetPort: 5349
    - name: smtp-25
      port: 25
      protocol: TCP
      targetPort: 12525
    - name: smtp-465
      port: 465
      protocol: TCP
      targetPort: 10465
    - name: smtp-587
      port: 587
      protocol: TCP
      targetPort: 10587
    - name: imaps
      port: 993
      protocol: TCP
      targetPort: 10993

How do I set the HAProxy ingress controller to use the PROXY Protocol with these TCP services? I don’t see anything you can set in the ConfigMap or LoadBalancer ports. Is there a way to set a backend snippet for a TCP service?
