I wonder whether this is the same course that Guillaume did a few years ago. On his biography page it is described as "From 2018 to 2019, Prince Guillaume followed a postgraduate course at the Royal College of Defence Studies (RCDS) in London, where he acquired additional expertise in regards to his future responsibilities as Head of State.", so that would fit this specific course as the Royal College of Defense Studies is part of the UK Defence Academy.
