TL;DR: yes

Just from a quick view of the repo, the simplest way to do it would be to look at the playbook.yml and copy all roles you want for a host into a new playbook, say myhost.yaml. Copy not only the roles but all the other keywords as well. Then you go to the inventory and add your hosts where you to execute the playbook against. Then you change the hosts key value in the playbook you made from all to the hosts you added to the inventory.

That is, add your hosts to the inventory, create playbooks for for them and run. That is the easiest. Read up on how to do groups and organizing your inventory to improve it from there.

How the government will respond to the Prison and Probation Service’s views remains to be seen.

They will not give a single fuck. They had basically every public sector union and other organisations saying “maybe we should not target children as a means to deport families”, and they did not give a shit. The want to see children of a darker shade in prison and nothing will stop them.
