When using a gateway provisioner, Contour can be configured through ContourDeployment

kind: GatewayClass
apiVersion: gateway.networking.k8s.io/v1beta1
metadata:
  name: mygatewayclass
spec:
  controllerName: projectcontour.io/gateway-controller
  parametersRef:
    kind: ContourDeployment
    group: projectcontour.io
    name: contour-with-envoy-deployment-params
    namespace: projectcontour
---
kind: ContourDeployment
apiVersion: projectcontour.io/v1alpha1
metadata:
  namespace: projectcontour
  name: contour-with-envoy-deployment-params
spec:
  runtimeSettings:
    envoy:
      logging:
        accessLogFormat: json
