Switching between AHCI and RAID on the Dell XPS 15 (9560)

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

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.

1. To set the default boot mode to Safe Mode, use msconfig.exe or open an admin cmd/PowerShell window and run:

#!/bin/bash
sudo sed -i "/\[org\/gnome\/desktop\/interface\]/a\clock-format=\'24h\'" /etc/gdm3/greeter.dconf-defaults
gsettings set org.gtk.Settings.FileChooser clock-format 24h
gsettings set org.gnome.desktop.interface clock-format 24h

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

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).

Testing colors

Running this script should look the same in tmux as without.
