Now that Divi has its own templating system it is recommended that you use Divi templates rather than Toolset templates.
With Divi templates, it offers dynamic sources for some of the modules, where the values displayed come from custom fields, for example.
That should work with content created with Toolset, e.g. in a template for a custom post type created with Toolset, output custom field values from fields created with Toolset. (Note, though, that they will output the raw values stored in the database, rather than the formatted versions output by Toolset blocks or shortcodes.)
Is there something specific you are trying that doesn't work?
