You'd have to write a bit of additional code to get that information. aws ec2 describe-instances will give you InstanceType property. You should use a programming language to parse the JSON, extract InstanceType and then call describe-instances like so: https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instance-types.html?highlight=nitro

From the JSON you get back, extract hypervisor. That'll give you Nitro if the instance is Nitro.

Here's a Python code that might work. I have not tested it fully but you can tweak this to get the results you want.
