How to set Kernel Parameters for Ubuntu 24.04.1 with TPM-backed FDE ?

[nquireery1100]

I’m currently exploring the new experimental feature of TPM-backed Full Disk Encryption (FDE) on Ubuntu 24.04.1 on a Thinkpad and would like some guidance on setting kernel parameters for my system.
From my understanding, this version utilizes UKI (Unified Kernel Image) and is managed via Snap, which is a bit different from the traditional approach of modifying GRUB.
Could anyone provide insights on:

1. How to set kernel parameters for a UKI-based system? Are there specific files or commands I need to use?
2. Any recommendations for kernel parameters that might be beneficial for optimizing TPM-backed FDE?
3. Potential pitfalls or considerations I should be aware of when implementing this feature?

Thank you for your help!

note i have searched the internet far and wide and have found nothing ! any help would be greatly appriciated !!

I guess it would be similar to Ubuntu Core:

I have yet to dig into it too much, though. I checked it to get hibernation working on FW13 Ultra Core, but It was too much of a task for something still experimental on 24.04.1, and when I wondered if it would stick around for the next LTS release.
