Here's how to compile and install the fairydust branch of the Asahi Linux kernel, to test out experimental DisplayPort over USB-C support. I wrote this for Gentoo, though it can be adapted for Asahi Fedora Remix, too.
git clone -b fairydust --single-branch --depth 1 https://github.com/AsahiLinux/linux.git
cd linux
These methods in this gist worked for me on my U.S.-based keyboard layouts. I am unsure about other layouts. If you have problems, revert your changes; delete the registry key you created (and reboot).
Update: you should probably scroll down to approach 4 where I suggest using Microsoft PowerToys Keyboard Manager.
Navigate to and create a new binary value in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout named Scancode Map.
