add_filter( \'site_url\', \'wpse_381006_custom_site_url\', 10, 1 );

function wpse_381006_custom_site_url( $url ){
    if( is_admin() ) // you probably don\'t want this in admin side
        return $url;

    // for example, return the request_uri - but this is not a complete solution, you would need to work out what you return and in what conditions..
    return $_SERVER[\'REQUEST_URI\'];

}
