What is the best way to install ansible on Ubuntu/Debian without internet?

Question

Debian

Good afternoon!
Tell me the "most correct" way to install ansible on Linux without the Internet.
Let me explain the situation in more detail: there is a company "A" that fundamentally does not want the Internet, but at the same time there is a great desire to manage a fleet of servers through Ansible. I can come to this company with a flash drive and somehow install Ansible.
How to download all Ansible dependencies and then install them on an offline server? )
Thank you in advance for your answers :)
