Update Container on macOS

I recently tried out the beta of Big Sur on a separate APFS container. I don’t need it anymore so I deleted the container. There is now one more container left called "Update". Does anyone know if this container belongs to Big Sur? Can I just delete it as well?

EDIT

This is the output of diskutil list:
