Don't look at the Anniversary update as just a single item patch. It's literally Windows 10.3. You'll need it to install next big patch, Redstone 2 (Or 1703, whatever you want to call it). That, or it will simply be a part of it.
You really can't avoid it, without effectively gimping your computer security-wise.
That said, what evidence indicates that you think its the anniversary update? I've troubleshot a couple hundred systems regarding that, from reboots to driver issues. I think you're better off solving the actual problem, than just avoiding the update. To date, I have not found a single unsolvable issue with the anniversary update.
