Minimize disk space per node

I have built a LibreNMS server with Oxidized integrated for config backups. I have found that each node I add to Libre uses 1.2-1.3 Gigabytes of disk space for the RRD graphs. I have thousands of nodes I would like to backup so the disk space require for that is not feasible unless I can find a way to reduce it.

I would like to minimize the amount of graphs created by excluding a bunch from the node-add template (I am making assumptions about templates) if possible. Can this be accomplished and if so, can you give me a little direction please?

Thank you in advance for any feedback.
