如何在.net Core3.1中的依赖注入设置之外将证书添加到IHttpClientFactory httpclient？

using System.Net.Http;
using System.Security.Cryptography.X509Certificates;

public void ConfigureServices(IServiceCollection services)
{
    // 注册IHttpClientFactory服务
    services.AddHttpClient();

    // 获取证书文件的字节数组
    byte[] certBytes = GetCertificateBytes();

    // 创建X509证书对象
    X509Certificate2 certificate = new X509Certificate2(certBytes, "certificate_password");

    // 创建HttpClientHandler并添加证书
    HttpClientHandler handler = new HttpClientHandler();
    handler.ClientCertificates.Add(certificate);

    // 配置HttpClient的Handler
    services.Configure<HttpClientFactoryOptions>(options =>
    {
        options.HttpClientActions.Add(client =>
        {
