This works for me. So long as you have a Kindle device registered on Amazon, you should be able to download directly to a desktop. The DeDRM plugin mentioned removes the DRM during ingestion into Calibre and requires an actual token from Amazon which is linked to the Kindle device you downloaded from.
I use this to get Amazon eBooks into my Remarkable 2 which requires DRM free.
