Per Amazon EC2 instance types, G6 is one of the supported instance types. However, it not an option in InstanceClass. The probable workaround is to use L1 construct.

@CambioML Thanks for bringing this issue into our attention. Feel free to contribute PR to add G6 EC2 instance type.

Before we have a PR to natively support that, you can override the InstanceType like this:

// create a dummy ec2 instance
    const instance = new ec2.Instance(this, 'Instance', {
      machineImage: ec2.MachineImage.latestAmazonLinux2023(),
      instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.SMALL),
      vpc: ec2.Vpc.fromLookup(this, 'Vpc', { isDefault: true }),
    });

   (instance.node.defaultChild as ec2.CfnInstance).addPropertyOverride('InstanceType', 'g6.xlarge');

verify:

% npx cdk synth dummy-stack1 | grep InstanceType
      InstanceType: g6.xlarge

And you will need to specify appropriate AMI as well.

Let me know if it works for you and we welcome any pull requests for this.
