This is a base64 encoded and zlib compressed binary value that must be properly encoded.</p> <p>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.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/uefi-secure-boot.html">UEFI Secure Boot</a> in the <i>Amazon EC2 User Guide</i>.</p>
The ID of the instance from which to retrieve the UEFI data.
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is <code>DryRunOperation</code>. Otherwise, it is <code>UnauthorizedOperation</code>.
