Backups error about charts-clickhouse HOT 1 OPEN

Found some ideas in backup repo, but this helm chart already defines CLICKHOUSE_HOST
Suggested solution is to set for backup clickhouse_host=127.0.0.1
I might "override" with clickhouse.backup.env, but which will stick, one in my values.yaml or from template?

• name: CLICKHOUSE_HOST
  value: {{ template "posthog.clickhouse.fullname" . }}

{{/*
Return clickhouse fullname
*/}}
{{- define "posthog.clickhouse.fullname" -}}
{{- if .Values.clickhouse.fullnameOverride -}}
{{- .Values.clickhouse.fullnameOverride | trunc 63 | trimSuffix "-" -}}
{{- else -}}
{{- printf "%s-%s" "clickhouse" .Release.Name | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{- end -}}
