How to send file directly to cURL PHP object storage?

Question

PHP

Good afternoon.
From the form, the file is uploaded to the server (ajax), after which it is uploaded to the Selectel object storage (PUT cURL php).
Tell me, is it possible to avoid uploading a file to an intermediate server and upload the file from the form immediately with cURL to the repository?
Thank you!

$curl = curl_init();
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt_array($curl, array(
    CURLOPT_URL => "https://api.selcdn.ru/v1/SEL_1337/test/Eprtst1.mp4",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "PUT",
    CURLOPT_POSTFIELDS => array('
' => new CURLFILE('test/upload/5ec46a241e58b.mp4')),
    CURLOPT_HTTPHEADER => array(
        "X-Auth-Token: 478493248"
    ),
));
