Thank you for posting in Microsoft Q&A forum.
Yes, we could add the sup role in the existing WSUS environment. When the software update point is configured, specify the synchronization settings. Configuration Manager connects to the WSUS server that runs on the software update point server and configures WSUS with the same settings. Please compare the configuration for products and classifications with your Configuration Manager settings. If you synchronized the existing WSUS server before configuring it as a software update point, and the lists of products and classifications are different, it syncs all of the software updates metadata regardless of the configured settings. This behavior results in unexpected software updates metadata in the site database.
For the sup configuration, please refer to this article:

Have a nice day!
