Probably you also could exchange the Pi currently for gold ;PIt comes with a Big Tree Tech Octopus controller, with TMC2209 drivers. No raspberry Pi with the kit. I had a Pi 4B on hand that I was using for Octoprint with my other printers.
Did you get yor motors right and already a print out of it?
