Delete Process Definition by Version

I have been looking at various documentation - and am trying to find a way to DELETE a process definition by VERSION.
I did find process definition deletion by KEY but thats not what I want. I’m looking to delete a specific version belonging to that key.
For example:
I have a process definitions called create-flow which has 9 listed versions in Cockpit. I want to delete version 9 only so that the process engine uses version 8.
How do I achieve this?

Hi @SemperFi1970,

Each version has a different process definition Id.
The link you referred to is about deleting by Id which is different than deleting by key and should serve your need
