HowTo: Disable Kindle KFX Encoding (2023-08)

Amazon has introduced a new form of Encoding/DRM called KFX. Apprentice Alf’s DeDRM Tools will no longer remove this. Luckily the project has been taken over by noDRM and a KFX_Input Plugin has been developed to allow calibre to remove the Kindle DRM.

Someone else has developed a method of disabling KFX within the Kindle app however this involves the Terminal and entering a command.
