Commvault Rest API to remove user databases from being backup

I am currently looking to automate some of our tedious task we do manually on commvault. One of which is removing the user DBs from being backup via commvault and deconfiguring a server from being backup if there are no active DBs on that server and vice versa. I started looking at this page here for available API that I can use to help with this PowerShell function I am looking to create. Was wondering if this is something doable as some of the API I saw on that page, I didn’t see one to remove user db from being backup if there are configured to be backed up. Any guidance with this would be greatly appreciated.
