Getting LUKS, Btrfs, Hibernation and Swap file working in tandem
I use sbupdate [0] to build the unified kernel image and to sign it with my keys. It's run by a hook in the arch's package manager whenever the kernel, the initrd or the firmware images change. I saw the other day that systemd recently got an utility to do this, but I've never looked into that. sbupdate has been working fine for me for several years now.
It doesn't store a new key in the uefi, it signs the new image with the key that uefi already knows about.
See [1] for the whole setup and [2] for the signing part specifically.

Can someone help me navigate the BIOS settings without display?
Here is where different systems will fork. On Arch there is a pacakge sbupdate where it automatically generate unified kernel images using pacman hooks and I use systemd-boot (which must be signed by your keys) to load it.

Windows 11 requiring to turn on Secure boot, making dual boot a little harder
I really think it's easy enough. You create your keys, put them into /etc/efi-keys, enroll them into your UEFI by whatever method you prefer, install sbupdate-git and you're done... You need to run sbupdate manually once after install, everything else works automatically through hooks.

I've moved to a new laptop with 3 NVMe drives, and I want full encryption and Secure Boot.
Ah, sbupdate does that very well; it embeds the kernel image, initramfs and the UEFI boot image into a unified signed image. I presume this signed image should then be further encrypted?

Unencrypted boot partition risks

Cool new things on linux world for fresh installation and a bit of my usage different things.
For the last part, check out https://github.com/andreyv/sbupdate . Linked also from arch wiki, so not some completely random solution. Its for creating unified kernel images, including the initramfs, microcode and so on. This package is then signed for secureboot, and can be loaded using EFISTUB for example. This prevents attacks against initramfs or some other things on /boot, if unencrypted. I haven't come around to test it myself, but I think its a neat solution, and with proper secure boot (and password protected firmware), a reasonable protection against evil maid attacks.

Security
I am using secure boot with custom keys, a fully encrypted root btrfs partition with /boot on it, with swap also encrypted with hibernation support. The only non-encrypted partition is the EFI partition with boot images signed with https://github.com/andreyv/sbupdate (look up "direct booting").

Current state of plugin managers
If you liked legacy antigen or antibody, and want something lightning fast, I recommend antidote (obviously, I'm biased here)

Introducing Antidote - A native zsh continuation of the antibody plugin manager
Hey everyone! I was pretty bummed out when antibody, the Zsh plugin manager I came to rely on, was deprecated last year and went into maintenance mode. It seems like all the Zsh plugin managers we've come to use and love have been disappearing or going into maintenance mode (antigen, zgen, zplug, zinit, etc). Thankfully projects like zdharma-continuum and Zgenom have been popping up to take over where others have left off (for zinit and zgen respectively), and new ones like Znap have come on the scene. But nothing showed up to give antibody users a compatible path forward. That changes now!

https://github.com/zdharma has suddenly disappeared. I haven't found any statement from Sebastian as to why. Sebastian Gniazdowski is the author of well know projects such as `zinit` and `fast-syntax-highlighting` and regular contributor to this community. Anyone have any background about why?
I use Antibody for that: https://getantibody.github.io/

Zsh Plugin managers
Antibody was mothballed. The author now points to other Zsh plugin managers as having caught up in speed to Antibody. See https://github.com/getantibody/antibody#maintenance-mode

Cool new things on linux world for fresh installation and a bit of my usage different things.
I set up my own config instead of using the grml one, so I use antibody for managing zsh plugins, and I use the following plugins:

The VSCode Insiders Build for Apple Silicon is ridiculously fast
Antibody is deprecated. Is there any other fast zsh plugin managers? I’m currently using Powerlevel10k’s instant prompt and oh-my-zsh.
What are some alternatives?
