Custom taxonomy with/without children

When using the /api/core/get_posts I am passing in a custom taxonomy. For some reason that I can’t explain, the SQL that is generated includes a where clause that includes the children under my custom taxonomy. And the same data on another server does not include the children.

If I was doing this using my own WP_Query, I would use the ‘include_queries’ clause.

array(
        'taxonomy' => 'tax_agreement',
        'field' => 'slug',
        'terms' => 'partnering',
        'include_children' => false,
        'operator' => 'IN'
      )

How might I pass in a query param that let’s me control the value of ‘include_children’?
