要确定AWS Centos 6.9和6.10 AMIs是否支持NVMe和ENA驱动程序，您可以使用以下代码示例来检查并打印出支持情况：

#!/bin/bash

AMI_ID=""  # 替换为您的AMI ID

# 检查是否支持NVMe驱动程序
nvme_support=$(aws ec2 describe-images --image-ids $AMI_ID --query 'Images[0].BlockDeviceMappings[0].Ebs.NvmeSupport' --output text)
if [ "$nvme_support" = "true" ]; then
  echo "AMI $AMI_ID supports NVMe"
else
  echo "AMI $AMI_ID does not support NVMe"
fi

# 检查是否支持ENA驱动程序
ena_support=$(aws ec2 describe-images --image-ids $AMI_ID --query 'Images[0].EnaSupport' --output text)
if [ "$ena_support" = "true" ]; then
  echo "AMI $AMI_ID supports ENA"
else
  echo "AMI $AMI_ID does not support ENA"
fi

请确保您已安装并配置了AWS CLI，并将替换为您要检查的AMI的实际ID。然后，运行脚本以获取AMI的NVMe和ENA支持情况。
