How to create an Ansible group with children, excluding a subset group?

I am using the Ansible EC2 Dynamic Inventory script to auto-generate groups.

This creates Ansible group ec2, that encompases all EC2 hosts in my AWS account.

A subset of those hosts have tag KubernetesCluster:kube-acceptance. The dynamic inventory script creates a group tag_KubernetesCluster_kube_acceptance.

I would like to construct an Ansible group including all hosts in group ec2, but excluding those in group tag_KubernetesCluster_kube_acceptance.

Can this be achieved in an inventory file?

Do you really need to create such a group or do you just want to use the resulting hosts in a playbook as described in your question?

A hosts definition in your play like this should do the latter:

- hosts: ec2:!tag_KubernetesCluster_kube_acceptance
  tasks: ...
