How to set up ssl via rest?

Question

Java

A dynamic SSL configuration has been created on IBM WebSphere, which embeds a certificate in outgoing requests, there is no need to write paths to jks in the code. How to set up sending the rest of the request so that the httpClient does not look for certificates in the IBM jdk if the request comes in https? Below is test code

CloseableHttpClient httpClient = null;
    HttpClientBuilder builder = HttpClientBuilder
            .create()
            .useSystemProperties();
            
    httpClient = builder.build();
    HttpPost request = new HttpPost("https://test.org:8081/add");

    // add request headers
    request.addHeader("custom-key", "rev");
    request.addHeader(HttpHeaders.USER_AGENT, "lebot");

    CloseableHttpResponse response = httpClient.execute(request);
