The only way to do this would be to add a filter to change the default name format. Here’s how.

Install the code Snippets plugin.

Add a new snippet with the following code:

add_filter( 'cn_output_family_atts', 'cn_output_family_atts' );

function cn_output_family_atts( $atts ) {

    $atts['name_format'] = '%first% %last%';

    return $atts;
}

Tweak the nam_format value as desired.

Save and Activate the snippet.

Hope that helps! Let me know.
