DSM on 2025 and later Plus series (and probably also DSM 8 for all models) does not allow you to:
- Set DSM to "Notify me and let me decide whether to install the new update".
- Set Package Center to not update packages automatically.
Synology have a provided a way, via SSH, to stop DSM or packages from updating automatically, but it stops both DSM and packages from auto updating. https://kb.synology.com/en-global/DSM/tutorial/stop_system_package_auto_update
