I kinda dislike the "level-up" corporate jargon but I understand what you mean. At the company I work for hack days can even be used for you to read technical literature, so if you'd like to take these 2 days to grok through a technical book you haven't found the time for you can do so. Is that encouraged where you work or does one need to "build" something out of these hack days?
