Why do you want to block it? If you have literally just bought it, install the update and do a factory reset. It will pretty much kill any chance you have of encountering issues plaguing many who are mostly trying to fix it without doing it. I've learned larger "software version" updates work best after a factory reset on android, even though they say in place upgrades work just fine. Minor software updates that just update a few apps seem to be less prone to issues.
A few moments on Google Image search would've nabbed you a screenshot with the info though :
