Provide functionality to update properties like we have in SSOM - SystemUpdate(false) - method. This would be most useful when updating items and not triggering an endless loop when using ItemCreated or modified action in Flow. Also, this is useful when you want to update metadata without causing another major or minor version.
Please refer to this idea that already suggested same or in some cases similar idea and was declined before. At this time, SharePoint product team has no plans to support system update capability for SharePoint Online.
