I’ve found an(other) solution with Curl.
<?php $test = get_field('logo'); ?>
<a href="<?php the_field('link'); ?>" target="_blank">
<?php $handle = curl_init();
curl_setopt($handle, CURLOPT_URL, $test);
curl_setopt($handle, CURLOPT_USERAGENT, 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:13.0) Gecko/20100101 Firefox/13.0.1');
curl_exec($handle);
curl_close($handle); ?>
</a>
My SVG files are loads inline now.
Hope this solution could helps someone.
