hi can you help me how to build script that i can deploy on intune that update onedrive version or downgrade the version. thank you

The above logic shows how to update a field in an XML file. My Azure DevOps Pipelines Version Extension also shows how to update fields in various JSON file formats.

I have no experience of OneDrive config files or intune so can't offer any more assistance
