I would like to make some housekeeping on some of our document libraries. Adding or changing a lot of metadata.
Of course I would like to do do this without changing modified and modified by columns. Otherwise we would have a mess with a bunch of old files surfacing as newly updated (simultaneously burying those who are actually new or updated).
As I understand this was possible on on-prem SharePoint using SystemUpdate, but also that this is not possible with SharePoint Online.
