You can use a TPM for disk encryption with Linux if you want. You also get to use your own secureboot keys if you want. Your choice.
I can't be bothered. My 80386 worked fine without any of the above and I still don't need any of it on a Zen%d (except Linux)
Yea I was looking at this for work. We require full disk encryption for all operating systems but linux is the one where it's a passphrase or a yubikey. In my personal life it would just make managing my PC more annoying. Imagine a motherboard failure and boom there goes my entire disk.
