If they are showing the same object on two different pages, you can just show everything in a single dataview on one page.

You can have only one page parameter, so for at least one data view you’ll need to provide the source by microflow or, when nested within the other one and if possible, by context and association. Or you can use a helper object as page parameter and get the objects for the dataviews from there. You can navigate to the page by microflow, create the helper object and associations in there and then show the page.
