How to not output the .pdb of the referenced project to the publish folder?

I want to keep .xml and .pdb in the debug and release folders, but not in the publish folder.

I know MSBuild has the following properties:
`PublishDocumentationFile` - Control whether the .xml file of the main project is published to the publish folder.
`PublishReferencesDocumentationFiles` - Control whether the .xml file of the referenced project is published to the publish folder.
`CopyOutputSymbolsToPublishDirectory` - Control whether the .pdb file of the main project is published to the publish folder.

But how to control whether the .pdb file of the referenced project is published to the publish folder?
I couldn't find the corresponding MSBuild property.
How should I do?
