This guide shows how to install Ansible on offline (blocked internet access) situations.
At this time, I installed Ansible 2.9 to CentOS 8.4.

Note: The entire procedures for setting up to manage Windows Server with Ansible are the following posts.

Preparations

Refer to the following post and make dnf (yum) command add packages from mounted DVD / ISO image.

Refer to the following post and install newer Python 3.x.
Note: Default Python3 version on RHEL 8.4 is Python 3.6.

(1) Download the following rpm files on an online (internet-accessible) environment.

Note: File name is as of the day I installed.

(2) Copy the downloaded rpm files to the server that Ansible is to be installed on.

Install rpm packages in sequence.

chmod 755 sshpass-1.06-9.el8.x86_64.rpm

dnf -y install sshpass-1.06-9.el8.x86_64.rpm

chmod 755 python3-httplib2-0.18.1-3.el7.noarch.rpm

dnf -y install python3-httplib2-0.18.1-3.el7.noarch.rpm

chmod 755 python-passlib-1.6.5-2.el7.noarch.rpm

dnf -y install python-passlib-1.6.5-2.el7.noarch.rpm

(1) Install rpm.

chmod 755 ansible-2.9.27-1.el8.noarch.rpm

dnf -y install ansible-2.9.27-1.el8.noarch.rpm

(2) Confirm that Ansible is installed correctly.

ansible --version

If it shows Ansible version, path of config file and so on like the following, installed successfully..

ansible 2.9.27
config file = /etc/ansible/ansible.cfg
