AWS ACM不支持为同一域名颁发多个证书。但是，可以使用AWS Elastic Load Balancer（ELB）为同一个域名使用多个证书。以下是一个示例：

1.创建两个ACM证书，分别用于验证该域名的不同内容。

2.将这两个证书附加到同一个ELB。

3.设置ELB以接受所有连接并根据请求中的Host头将其转发到适当的后端。

以下是用于创建ELB的CloudFormation模板示例：

Resources:
  MyELB:
    Type: "AWS::ElasticLoadBalancingV2::LoadBalancer"
    Properties:
      Name: my-elb
      Subnets:
        - subnet-xxxxxx
        - subnet-yyyyyy
      SecurityGroups: [ sg-1234abcd ]
      Type: network
      Scheme: internet-facing
      LoadBalancerAttributes:
        - Key: idle_timeout.timeout_seconds
          Value: '60'
      Tags:
        - Key: Name
          Value: my-elb
  HTTPListener:
    Type: "AWS::ElasticLoadBalancingV2::Listener"
    DependsOn: MyELB
    Properties:
      LoadBalancerArn: !Ref MyELB
      Port: 80
      Protocol: TCP
      DefaultActions:
        - Type: fixed-response
          FixedResponseConfig:
            ContentType: 'text/plain'
            MessageBody: 'Hello, world!'
            StatusCode: '200'
  HTTPSListener:
    Type: "AWS::ElasticLoadBalancingV2::Listener"
    DependsOn: MyELB
    Properties:
      LoadBalancerArn: !Ref MyELB
      Port: 443
      Protocol: TCP
      Certificates:
        - CertificateArn: "arn:aws:acm:us-west-2:123456789012:certificate/xxxxxxxx-yyyy-zzzz-aaaa-bbbbbbbbcccc"
        - CertificateArn: "arn:aws:acm:us-west-2:123456789012:certificate/aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
