Unable to connect to GCP Redis with SSL enabled. Is there any way to pass .Pem Certifcate in spring configs?

Question

currently this is how I am connecting with redis..If someone can let me know how to configure ssl options to use .pem certificate will be very useful

  @Bean
  LettuceConnectionFactory redisConnectionFactory() {
    final SocketOptions socketOptions = SocketOptions.builder()
      .keepAlive(true).build();
    final ClientOptions clientOptions = ClientOptions.builder()
      .socketOptions(socketOptions).build();
    LettuceClientConfiguration clientConfig = redisUtil.isSslEnable()? LettuceClientConfiguration.builder()
      .clientOptions(clientOptions).useSsl().build():LettuceClientConfiguration.builder()
      .clientOptions(clientOptions).build();
    RedisStandaloneConfiguration serverConfig = new RedisStandaloneConfiguration(redisUtil.getHost(),
      redisUtil.getPort());
    serverConfig.setPassword(redisUtil.getKey());
    return new LettuceConnectionFactory(serverConfig, clientConfig);
  }
