Turns out the setting is in the Control Panel. It’s under Control Panel > System and Security > SupportAssist OS Recovery > Settings. 
I remember a while ago I was able to change how big these backups would be but I can't figure out how to get back there. TreeSize shows me SupportAssist's definitely taking backups (I can see where they are) but I can't figure out how to change the settings for them. Any ideas?

Does SupportAssist create backups ("snapshots")? Where can I change the 
settings for them?
