This guide likely applies to other models and, potentially, even laptops from other OEMs that have NVME drives. However, I've only tested this on my Dell XPS 15 (9560) with the OEM Windows installation from the Signature Edition model.
Switching from RAID to AHCI is significantly simpler than switching from AHCI to RAID. All that's needed is a successful boot to Safe Mode.
msconfig.exe or open an admin cmd/PowerShell window and run:

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).
Running this script should look the same in tmux as without.

Ubuntu Desktop 20.04 supports a single ZFS boot drive out of the box. I wanted a ZFS mirror, without going through an entirely manual setup of Ubuntu as described by OpenZFS
This adds a mirror to an existing Ubuntu ZFS boot drive after the fact.
ZFS requires native encryption to be added at pool / dataset creation. Ubuntu 21.04 supports this during installation. Whether these instructions are suitable for mirroring such a setup has not been tested. For Ubuntu 20.04, these instructions are not suitable for creating an encrypted ZFS boot disk, please use the full instructions linked above for that. You can, however, add an encrypted dataset after the fact: You could encrypt just the portion of your file system that holds secrets.
Note: If your use case is running docker instances, and not a full-fledged Ubuntu install, then take a look at TrueNAS SCALE
