Hi Mile P,
Thank you for reaching out to us. I am Blessing, an independent advisor here and a Microsoft user like you.
Microsoft AutoUpdate provides updates to various Mac products from Microsoft.
Yes you can disable Updates:
First, launch Finder and type microsoft autoupdate in the search bar, Microsoft AutoUpdate from any Office programs Help menu then Check for Updates. Uncheck the box 'Automatically keep Microsoft Apps up to date'
Or choose ‘Advanced’ where you can choose which type of Office to get. Production is the usual or one of the Insiders options.
Make sure ‘Automatically download and install’ is OFF.
Updates to the Office apps are disabled until specifically re-enabled.
To enable automatic update, find link below:
