How to modify the YAML file of an action?

I created a multi-node Kubernetes cluster using Kind and deployed OpenWhisk using Helm. My requirement is to run some actions on one worker node and other actions on another worker node. I noticed that after invoking an action, it creates a pod and assigns a worker node. How do I modify the Node Affinity in the YAML of this pod?

The following is a partial screenshot of the YAML.Use the command `kubectl get pod wskowdev-invoker-00-62-guest-test -n openwhisk -o yaml`

Start with the Helm deployment and inspect the generated pod YAML using `kubectl get pod wskowdev-invoker-00-62-guest-test -n openwhisk -o yaml`. Trace where the pod configuration is produced and determine whether node affinity can be configured through the deployment inputs; done means documenting the supported configuration path for assigning actions to worker nodes.
