Magento 2 How to turn off SSL check on sending CURL request to the external API?

I am working on a module that will send CURL requests to the external APIs of a CRM. I am getting an error in my exception log like main.CRITICAL: Error Curl {"exception":"[object] (Exception(code: 0): SSL certificate problem: self signed certificate at /httpdocs/vendor/magento/framework/HTTP/Client/Curl.php:427)"} [] does anyone have any idea why is this appening? And how can I solve this issue?

request format

$url="https://sample.com:8000/burst/int/so/control/salesProcess";
      $authorization = "Authorization: Bearer vr5HmMkzlxKE70W1y4MibiJUusZwZC25NOVBEx3BD1";
      //$headers = ["Content-Type" => "application/json", "Content-Length" => "200", $authorization];
          $headers = ["Content-Type" => "application/json", "Accept" => "application/json", "Content-Length" => "200", CURLOPT_RETURNTRANSFER => true, CURLOPT_FOLLOWLOCATION => 1, $authorization ,"CURLOPT_CONNECTTIMEOUT"=>120, "CURLOPT_SSL_VERIFYPEER"=>false];
      $params = ' {
    "ApiContext": {
        "application": "ecommerce",
        "applicationId": "123456789",
        "txnid": "STOCK_ISSUE",
        "txprotocol": "SYNC",

    "ApiMandatoryParams": {
        "sales_issue": '.json_encode($result).
        
    '},
    "ApiAdditionalParams": {}
}';
        
        //if the method is get
        $this->curl->get($url);
        $this->curl->setHeaders($headers);
        $this->curl->post($url, $params);
        //response will contain the output in form of JSON string
        $response = $this->curl->getBody();
       // $responseArr = $response->__toArray();
        $em  =  array();
        $this->logger->addDebug($response,$em);
    }
    catch (Exception $e) {
        $this->logger->critical('Error Curl', ['exception' => $e]);
    }
