How can I boot using Ansible on an Dell iDRAC9 server from an iso that's located on a remote server?

I have this playbook that what I'm trying to do it's to install CentOS using Ansible and Redfish, I don't want to use any modules, I'll install the CentOS on multiple Dell iDRAC9 servers and I'm having one issue:

2)After the ISO it's mounted, the server has not entered automatically into ISO boot menu, and I'm trying to achieve this by the Set ISO as primary boot device task.

Can someone please help me to correct this?

Here's the code:

- hosts: Linux_OS_machine
  connection: local
  name: ULP image install
  gather_facts: false
  vars:
    ansible_python_interpreter: /usr/bin/env python
    datatype: SetBiosAttributes
    image: "{{ iso_version }}-{{ inventory_hostname }}.iso"

I have been able to accomplish an OS Deployment to iDRAC9 using the dellemc.openmanage collection. Add the collection via ansible galaxy commands then from a playbook, import the role dellemc.openmanage.idrac_os_deployment. https://github.com/dell/dellemc-openmanage-ansible-modules/blob/collections/playbooks/idrac/idrac_os_deployment.yml

If you haven't figured it out yet, I can work on putting my project into Gitlab to give you an idea of what to do. Let me know
