[PopOS LTS 22.04]: Surface Laptop 4 peripheral non-functional after install - stage initial disk decryption

[GloverChris]

Found a problem in PopOS LTS 22.04. Would you like me to submit a bug report to the official rep? (Happy to see if I can just pr the fix myself if you'd like).

Problem: ⌨️💽

After install, when you reboot the machine and get greeted with a prompt to decrypt disk, there are no drivers loaded for the laptop keyboard or mouse.

Workaround: 🧑‍🏭

If plugging in a keyboard that uses generic keyboard drivers, you'll be able to decrypt disk. Upon successful decryption you will then be able to use laptops built in mouse and keyboard.

Thoughts\Observations: 🕵️

I believe what's happening here is that drivers for mouse and keyboard are not able to load due to disk not being decrypted to be able to load the special drivers. This would explain why keyboards that support generic drivers work. This leads me to believe the mouse and keyboard may not be using generic drivers to work

@jackpot51 and @mmstick hey friends, I found this bug and want to help fix it. This is my first time contributing to a distro, not sure if you have any guidance. My assumption is there is some sort of load_driver sequence in a function or macro somewhere, but I am having a tough time locating where that is. Thanks in advance for any help and hopefully I am not overstepping in some way here.
