You can always turn the handlebars ?
Fyi, For many if not most bikes built within the past 10-15 years the small hex bolt you see at the top of the handlebar stem actually also tensions the steering tube bearing within the bike stem. Although you could turn the handlebars by removing that cap and usually a couple of hex bolts on the side of the upper handlebar attachment, you have to torque it back in place at somewhat low levels like 5-nm or less to reload the steering tube bearing. It's not a process you want to do on a regular basis for risk of stripping threads. The handlebar stem attachment on new bikes is often aluminum. Be aware that this can vary significantly by age of bike and manufacturer.
Probably more than you want to know about bike construction but by removing those 3 bolts and lifting off the handlebars you can usually easily drop/remove the entire front fork through the bottom. Pretty nifty and simple construction which now allows many companies to design and sell their own bike frame (Trek, Specialized, and smaller bike manufacturers) but obtain forks from a third-party producer.
