I found that this is easily done but rather than remove my post, thought to address the solution here should anyone else run into this.
1. Create a separate folder on your server for "Family Videos", and add this as a separate data source. (shared folder) in Serviio
2. Disable the "Retrieve Descriptive Metadata" box for this source in Serviio
The files in this folder will not be defined as series or Movies in Serviio, but can be viewed using the "Folders" option.
