Could you please allow OneNote Teams tab configuration via the Graph API? I ran into a situation where my management asked me to setup a template Microsoft Teams channel to create future channels within the same team. The template channel had a tab pointing to a OneNote notebook. While I am able to cycle through the tabs in the template channel and read their configuration, as it turned out, I cannot use that configuration info to setup the same tab within a new channel.
I don't see this being any different than the custom/web tab. Please allow OneNote configuration in your JSON payload.
In addition to the above mentioned. Here is the link/reference where is stated that configuration is currently not supported: https://docs.microsoft.com/en-us/graph/teams-configuring-builtin-tabs#onenote-tabs
