GET

/#Action=GetInstanceUefiData

http://ec2.{region}.amazonaws.com/#Action=GetInstanceUefiData

A binary representation of the UEFI variable store. Only non-volatile variables are stored. This is a base64 encoded and zlib compressed binary value that must be properly encoded. When you use <a href="https://docs.aws.amazon.com/cli/latest/reference/ec2/register-image.html">register-image</a> to create an AMI, you can create an exact copy of your variable store by passing the UEFI data in the <code>UefiData</code> parameter. You can modify the UEFI data by using the <a href="https://github.com/awslabs/python-uefivars">python-uefivars tool</a> on GitHub. You can use the tool to convert the UEFI data into a human-readable format (JSON), which you can inspect and modify, and then convert back into the binary format to use with register-image. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/uefi-secure-boot.html">UEFI Secure Boot</a> in the Amazon EC2 User Guide.
