Disable 'Update Available' notification

I would like to disable this notification bubble:
2022-10-05 11.15.52

As I’m using my system package manager to install obsidian I have no need of a separate update checker, and this notification is annoying to clear every startup.

I’ve tried turning off ‘Automatic updates’ in Settings → About, yet the issue persists.

Any suggestions?
