如何使用CURL_SETOPT将CURL路由到另一个IP地址？

I am using mailchimp plugin to connect my woocommerce site to their platform but my server's IP address is getting blocked by Akamai, a third party security layer that their API routes through. I have been told that the only way I can use mailchimp is to change the IP address that the API calls are going through. So now I'm trying to hack the plugin to do this. I believe what I need to do is use curl setopt but I have no idea how to use it within this code. Anyone have any ideas? I'm almost positive I put it in is this block of code somewhere but I don't know the proper syntax.

protected function put($url, $body)
{
    $curl = curl_init();

    $json = json_encode($body);

    $options = $this->applyCurlOptions('PUT', $url, array(), array(
        'Expect:',
        'Content-Length: '.strlen($json),
    ));

    $options[CURLOPT_POSTFIELDS] = $json;

    curl_setopt_array($curl, $options);

    return $this->processCurlResponse($curl);
}

The best solution is to enable FREE cloudflare service on your website by signing up with CloudFlare. On activation of cloudflare your website IP will be atomatically changed to cloudflare proxy IP address and you will then find website IP via hostname to IP and communicate with API without any need of changing your server IP.
