You may modify user data using the af/form/editing/user_data filter. To conditionally modify a user role based on a submitted value, use the af_get_field() function within the hooked callback as per the following example:

add_filter( 'af/form/editing/user_data', function ( $user_data, $form, $args ) {

  // If we aren't handling the desired form, return early.
  if ( $form['key'] !== 'FORM_KEY_HERE' ) {
    return $user_data;
  }

  // If a submitted value matches a condition, modify the user role.
  if ( af_get_field( 'some_submitted_field' ) === 'some value' ) {
    $user_data['role'] = 'author';
  }

  return $user_data;
}, 10, 3 );
