Replace CDN Image-URL

Hello,

I have switched from Yoast to Rank Math and so far everything has worked fine.
However, I still have a question about using a CDN.
With Yoast I have made the following adjustment:

/* Yoast-KeyCDN*/
function wpseo_cdn_filter( $uri ) {
return str_replace( 'https://site.de', 'https://site-19000.kxcdn.com', $uri );
}
add_filter( 'wpseo_xml_sitemap_img_src', 'wpseo_cdn_filter' );

Is there a similar customization for Rank Math?
