No. It's not a standard feature of Ansible. Just the opposite, in
most cases the goal is to make a playbook idempotent. There should be
no changes reported when running a playbook repeatedly.

It depends on the module and it might be configurable. For example,
the module *file* allows to preserve *access_time* and
*modification_time* because you might want to configure them depending
on your use case.
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/file_module.html

Try to find out which Ansible module(s) is/are causing the troubles.
The task should report 'changed: true'. For example, the task below
(running at localhost only)
  
    - file:
        state: touch
        path: /tmp/test

will repeatedly report 'changed'

  TASK [file] ************************************************
  changed: [localhost]

The task will become idempotent when you set both *access_time* and
*modification_time* to 'preserve'

    - file:
        state: touch
        path: /tmp/test
        access_time: preserve
        modification_time: preserve

To move on, it will be necessary to learn details.
