Can You Render Data from Forced Fields in Views While Using format "Show: Content" Drupal 8.x

Is it possible to render fields in a view when the display format setting is set to format "Show: Content" ?

For my case, the contrib module I am using has some views integration that provides field data I would like to show, but have found to be difficult to access via preprocess. I also have some programmatically created data I need to show via my template provided by a HOOK_preprocess_HOOK().

I am kind of stuck in the middle. So I am curious if there is a way to render, or maybe get the data of, the forced fields while setting my view to "format: content"?
Yes, you have to decide whether you want to render Content or Fields. Those are two different concepts in Views. The first renders the entity template in the selected view mode and you configure the fields in the content type. The second renders Views field plugins which you configure in Views UI.

You can approach the issue from both sides:

Show: Content | View Mode

If you start with a View showing content, in the view mode you've selected, display a field for a second View dispay of the same entity. In the second View display select Show: Fields.

You need a module to add the View field to the content type, for example  EVA: Entity Views Attachment or Views Reference Field.

Show: Fields | Settings

Or start with showing fields,  add a field for the rendered entity 



and select a view mode, which you then can configure, preprocess and theme like a normal node template.
