Typography: Possible to choose font categories?

Is there any way to set which font categories can be included or excluded in the typography options? I don’t see it in the docs but I tried anyway, by adding it as a default. I was attempting to exclude Display fonts.

Kirki::add_field( 'content_google_font', array(
  'type'        => 'typography',
  'settings'    => 'content_google_font',
  // 'label'       => esc_attr__( 'Content', 'textdomain' ),
  'section'     => 'fonts',
  'default'     => array(
    'font-family'   => 'Slabo 13px',
    'variant'       => 'standard',
    'category'      => array(
    // 'categories'      => array(
      'serif',
      'sans-serif',
      'handwriting',
      'monospace',
    ),
  ),
  'priority'    => $priority++,
  'choices' => array(
    'fonts' => array(
      'standard' => array(
        'serif',
        'sans-serif',
        'monospace',
      ),
    ),
  ),
  'transport'		=> 'auto',
  'output'      => array(
    array(
      'element' => 'body',
    )
  ),
));

You can see I tried both “category” and “categories”, but of course neither of them worked. Is there such an option and, if so, how can I implement it?

If not, it seems this would be a much desired option for those of us who don’t want end users writing all their blog posts in, say, Libre Barcode. 😮
