Thank you for your post and I apologize for the delayed response! When it comes to uninstalling the Azure Information Protection (classic) client via SCCM, I wasn't able to find any documentation on this, so I don't believe this is possible, but you should be able to follow the steps below to uninstall the Azure Information Protection (classic) client.
You can uninstall the Azure Information Protection (classic) client using any of the following options:
- Use Control Panel to uninstall a program: Click Microsoft Azure Information Protection > Uninstall
- Rerun the executable (for example, AzInfoProtection.exe), and from the Modify Setup page, click Uninstall.
- Run the executable with /uninstall. For example: AzInfoProtection.exe /uninstall

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
