How to disable scheduled maintenance?

I use Kopia (through Kopia-UI) for manual, local, daily backups on a Windows laptop. The repository is on an external mass storage device that is only connected when doing the backup. After update Kopia-UI is now sending me spurious notifications about repository maintenance errors, and the task log in app is polluted with failed maintenance attempts, because the device the repository is on is disconnected.

Short of disconnecting the repository every time and having to add it back every time, how can I disable this maintenance?

Note: I have other regular backups for this computer, this manual backup scheme is a specific component of my backup regimen and I am not willing to alter how I do it, it is an important part of my workflow. Please don’t make suggestions about that or otherwise about my backup routines. Thanks.

It looks like these commands did the trick:

%LOCALAPPDATA%\Programs\KopiaUI\resources\server\kopia.exe --config-file=%APPDATA%\kopia\repository.config maintenance set --enable-full=false
%LOCALAPPDATA%\Programs\KopiaUI\resources\server\kopia.exe --config-file=%APPDATA%\kopia\repository.config maintenance set --enable-quick=false

I had to quit and restart Kopia UI background applet for the change to take effect.

It would be nice if there was a way to manage this through Kopia-UI itself.
