2019 Mondo front ballast upgrade

So, I got a new (to me) boat - 2019 Mondo, and she is my first inboard. I quickly realized I need to upgrade her ballast, but after surfing the forum I am still not able to quite figure how to upgrade the front ballast. Requirements: it has to be hidden, so need to go either underfloor or to the front lockers and integrate with existing pumps / overflow.
Was looking at Wakemakers Piggyback but couldn't quite figure what exactly setup is needed, if it is hidden and what the installation procedure is.
Any pointers please?
