Can Do Not Disturb Mode on iOS 7 while iPhone 5S is unlocked prevent notifications?

Can anyone tell me if there is a setting that would allow me to prevent notifications on iOS 7 while in Do Not Disturb mode and while the phone is unlocked? I use my phone on dock as both my clock and alarm at night. Last night, I was woken up at 1am because the screen on my phone lighted up with a notice that there is an iOS 7.0.2 update available, asking me to make a selection. This was really annoying. Is this just something that Do Not Disturb cannot control or is there something I can select to prevent this from happening in the future? Thanks.
