TCP CRD - log_level: silent not working?

[GilchristT]

I'm using the TCP CRD version 3.1 installed using the raw manifest https://www.haproxy.com/documentation/kubernetes-ingress/community/crd/v3-1/ingress.v1.haproxy.org_tcps.yaml

It's up and running fine but I've one particularly noisy ingress that I don't want the logs from but I can't find any way to silence it.

If I'm reading the documentation at https://www.haproxy.com/documentation/kubernetes-ingress/community/configuration-reference/tcps-crd/#frontend-tcp_request_rule_list-version-v3-1 correctly, the correct incantation is

spec:
- name: my-rule-name
  tcp_request_rule_list:
  - log_level: silent

but this isn't working. I've also tried log_level: silent in the frontend section but it hasn't worked either.

See below for my full TCP ingress definition. I've shown all combinations I've tried but I've tried them all separately e.g., just tcp_request_rule, just defining log_level: silent in the frontend section, with and without the log_format, etc.

apiVersion: ingress.v1.haproxy.org/v1
kind: TCP
metadata:
  name: zabbix-server-tcp
  annotations:
    ingress.class: haproxy
spec:
- name: zabbix-10051
  tcp_request_rule_list:
  - log_level: silent
  frontend:
    log_level: silent
    name: zabbix-frontend
    log_format: "%{+json}o %(log_bucket)[str(zabbix)] %(haproxy_log_type)[str(tcp)] %(target_ip)si %(target_port)sp %(source_ip)ci %(bytes_read)B %(bytes_uploaded)U %(request_sni)[ssl_fc_sni] %(time_active)Ta %(termination_state)ts"
    binds:
    - name: zabbix-10051-bind
      port: 10051
  service:
    name: zabbix-server
    port: 10051

Any assistance greatly appreciated
