+The webhooks are enabled by default, if you want to disable it, you can update the `operator.yaml` file and set the
+`ENABLE_WEBHOOKS` variable to `false`, it can be done quickly with the following command:
+[source,shell]
+----
+curl https://raw.githubusercontent.com/kiegroup/kogito-serverless-operator/{operator_version}/operator.yaml -o operator.yaml
+sed -i '/name: ENABLE_WEBHOOKS/{n;s/value: "true"/value: "false"/}' operator.yaml
+----
+
+And install the operator using this downloaded `operator.yaml` file.
+[source,shell]
+----
+kubectl apply -f operator.yaml
+----
+
+After it is installed, there will be needed to manually delete the webhooks:
+
+[source,shell]
+----
+kubectl delete mutatingwebhookconfiguration.admissionregistration.k8s.io/kogito-serverless-operator-mutating-webhook-configuration
+kubectl delete validatingwebhookconfiguration.admissionregistration.k8s.io/kogito-serverless-operator-validating-webhook-configuration
