Microsoft Purview Sensitivity Label with Digital signature
Currently if a PDF file is digitially signed, we cannot change the Purview sensitivity label without impacting digital signature.
We are looking to have a feature developed to modify / create sensitivity label without impacting digital signature in the pdf's.
This feature is required. because we are required to apply specific sensitivity labels when documents are shared externally.

According to Microsoft, "Sensitivity labels don't support signed PDFs." --- https://learn.microsoft.com/en-us/purview/sensitivity-labels-sharepoint-onedrive-files#adding-support-for-pdf
Apparently the feature you require has not been an objective when Microsoft had designed the sensitivity label system.
