I'm going to assume you have a model of Creo whose Future Shock fork steerer is aluminum(?). If your bike has a carbon fibre steerer then the solutions would be different.
Glancing at the Creo models on the Specialized website, it looks like they all have a standard removable faceplate stem for a 31.8 bar (now standard) and a 28.6mm/1.125" steerer (also pretty standard). If so, it means you can choose a riser stem to raise your bars. I've linked a couple below that both focus on raising the bar, but there are many threadless riser stems out there on the market to consider.
Before you get a new stem, look at your installed stem to see if flipping it will use a higher rise? It depends on the stem--the stock stems on the Creo models on the Specialized website look 90 deg or pretty close which means their angle won't change if you flip it :-( Post a photo of your bike and folks here can help you determine that. Most threadless stems work fine inverted--the one on my attached photo above was flipped from stock to lower it and the difference in height was 3-4cm.
Here's one that adds instant height and looks good: Velo Orange's Happy Stem. They offer choices of 9cm or 11cm extension and silver or black. If your Creo stem set-up is the same as the stock models on the Specialized page, this could be a 5 minute install replacing your stock stem.

For someone who needed a lot of height, there are stems in this swan neck shape:
Get your bars up high with the Cigne Stem. The design is inspired by gooseneck and LD stems by Ibis and Cunningham, but with a 31.8mm 2-bolt removable faceplate.

There are now good quality handlebars that have some rise built in. I learned about this Soma Condor bar (below) from EBR member PedalUma. The stock Creo handlebars I see on their site already have some rise built in so maybe this would not add enough. Plus it would require more install complications to move levers and tape over from old bar to new bar. The name riser drop bar contains a contradiction that makes me smile so I consider that a plus ;-)
If you haven't replaced a threadless removable face-place stem before, I or someone here on EBR can describe the process and you can decide if you want to try it. Very simple and it's good for riders to know how to fix/adjut their stems, but it is is a critical bike part you want to get right
before you ride ;-)
Edit: Ah, my reply was slow and you already have posted your photos and answered the stem-flip question. Yes, I think you're right your stock stem is already in the position where it would have most rise. From your photos it looks like a carbon frame/fork but the stock stem looks like the kind of conventional aluminum alloy stem that gets installed on an aluminum steerer. I treat carbon steerers with kid gloves, but it may be that this kind of aluminum alloy stem gets installed on carbon steerers too. Either way, this aluminum stem attached below is essentially the same thing made from the same metal as your stock stem, so I don't see a reason you couldn't switch one to the other.
