 is delegated to YuniKorn. You can disable it by setting `embedAdmissionController` flag to `false` during the helm install.
 
-The YuniKorn scheduler can also be deployed as a Kubernetes scheduler plugin by setting the Helm `enableSchedulerPlugin`

 helm install yunikorn yunikorn/yunikorn --namespace yunikorn --version {version}
