When reading the instructions for setting up a CloudFormation Template in Creating and Using a Jupyter Instance on AWS, I find the following modification difficult.

"AWSRegionArch2AMI" : {
  "ap-southeast-2" : {"HVM64" : "ami-58facb3b", "HVMG2" : "ami-6cfdcc0f"}
}

I've set up an AMI running on Amazon Linux 2 with instance type "c5d.2xlarge". Which HVM (HVM64, HVMG2, HVMP2) should be chosen?

I've read How do I specify in an AWS Cloudformation template that my t1.micro instances are 64-bit architecture, and I've tried searching the sample CloudFormation template in the linked PDF, but there's no c5d.2xlarge in AWSInstanceType2Arch. The official docs simply say that it's related to the AMI's architechture without further explanations.

For c5d.2xlarge choose HVM64.

The HVMG2 is for instances of g2.* / g3.* GPU-optimised family, similarly HVMP2 is for p2.* and p3.* families.

However the AMI IDs for Amazon Linux 2 are different than the above, check this out: https://aws.amazon.com/amazon-linux-ami/

Hope that helps :)
