[Question] Do I need a Bypasser for a Non-Battleye enabled server?

I'm new to the scripting world and, the question says it all.

I intend on joining a non-battleye enabled server to grab a few items and eventually reset my humanity with a script I found.

BUT, I've read somewhere that battleye is serverside AND client side.... is this true?
In that case, would I still need a bypasser?

Norton utilities also blocks the un-zippage of the DayzNavigator v2 and v2.1 because of something called infostealer.gamepass
I generally trust Norton who says this is a threat, but could I just be a n00b, so this file is necessary and safe?

Any file that approved on this site 99% of the time is safe. But any server not enabling battleye isn't on the hive. So you can't grab items or reset your humanity then go back playing on a hive server with that stuff.

If BattlEye is disabled on a server, it does not connect to the DayZ hive. Meaning, you can spawn to your heart's content but your character stored on the official hive will remain unchanged.
