Yes, you can. If you use a clean Nexus build then last time I tried it, the behaviour was that the first time I opened Chrome it asked me if I wanted to sign in to chrome to share my history and bookmarks between devices, and I had a simple yes/no choice. I don't think this needed any deep technical knowledge.
I'm not intimately familiar with the android chrome settings UI, so I apologise if I've missed an easier way, but in about 30 seconds of tapping I found the button to turn it off: main settings page, accounts, my google account, sync, uncheck chrome.
