There's a setting for the network connection for 'metered'.
This will prevent any and all automatic system and app updates from occurring, so you would have to initiate them manually in both Settings (for system updates) and Microsoft Store (for apps). Likewise, if you have MS Office, it will notifiy you that updates for that are available (sometimes erroneously, btw), however it won't actually update anything unless Metered is temporarily switched off, then re-engaged after it's done.
