Use the \Magento\Catalog\Block\Product\ProductList\Toolbar::setDefaultDirection() method:

github.com

magento/magento2/blob/d447fa6e1/app/code/Magento/Catalog/Block/Product/ProductList/Toolbar.php#L292-L304


/**
 * Set default sort direction
 *
 * @param string $dir
 * @return $this
 */
public function setDefaultDirection($dir)
{
    if (in_array(strtolower($dir), ['asc', 'desc'])) {
        $this->_direction = strtolower($dir);
    }
    return $this;
}

For a detailed description see how is the «Sort By» control implemented on the frontend product lists.

If you will change a core file then it will break the possibility to update Magento, or your changes will be broken by a Magento update.
