add_filter( 'woocommerce_composite_component_options_query_args_current', 'sw_cp_exclude_out_of_stock_options' );

function sw_cp_exclude_out_of_stock_options( $args ) {
    $args[ 'exclude_out_of_stock' ] = true;
    return $args;
}

Is there the possibility of modifying this code to exclude "On Backorder" products from the component options? I've tried: `
// Hide backorder products Composite Options
add_filter( 'woocommerce_composite_component_options_query_args_current', 'sw_cp_exclude_is_on_backorder_options' );

function sw_cp_exclude_is_on_backorder_options ( $args ) {
$args[ 'exclude_is_on_backorder' ] = true;
return $args;
}
`

but this has not worked. Thanks
