Need technical article on steps to automate installation of Ubuntu 20.04

I am looking for articles very specific to following topics

1. Configure IPv4 UEFI PXE BIOS using Kickstart in Ubuntu 20.04
2. Configure IPv6 UEFI PXE BIOS using Kickstart in Ubuntu 20.04
3. Configure IPv4 Legacy BIOS PXE BIOS using Kickstart in Ubuntu 20.04
4. Configure auto install for Ubuntu 20.04 using cloud-init user data configuration

The article should contain all the screenshots and proof of the PXE installation success at the end.

In your submission if you can brief me the steps involved in performing automated installation of Ubuntu using kickstart then it would help me understand that you have the required knowledge in this area

Also I would like to know if you have environment with UEFI BIOS (IPv4 and IPv6) network to test the steps?
