GKE "Enable auto-upgrade" setting cannot be toggled off

I use GKE to host and manage a kubernetes cluster. GKE will update it's nodes automatically by default. Per this documentation the setting can be toggled on or off. (https://cloud.google.com/kubernetes-engine/docs/how-to/node-auto-upgrades)

However, I am unable to disable this feature. The option is grayed out. Does anyone know why? I have been unsuccessful in finding documentation or answers online.

Surely as soon as I humble myself and publicly ask a question I find the answer on my own. :-)

First the Cluster "Release Channel" needs to be set to a specific version. Once this is set you will be able to change the behavior of the node pools.

Previous speaker is right. Below the answer from google support service to my request:

Node-auto-upgrades are always enabled if your cluster is enrolled in a release channel. You will find this information on this part of the document. You will need to set that configuration to a static channel before trying to disable the nodes auto-upgrades. You can find this configuration to be edited here in your cluster information panel.
