This worked perfectly thank you!

Hello everyone!
I just wanted to inform you that I've created a bash script designed to automate the process of disabling cloud-init on Ubuntu servers. It's a quick and simple solution you can even call through a oneliner.

Give it a try and let me know your thoughts! Your feedback is highly appreciated.

After purged cloud-init (on 22.04), the netplan package is also removed.
I followed this section 3.3. Temporary Static IP via ip
to temporary get an IP address, then reinstall netplan using: sudo apt install netplan.io
