No, it isn't possible to turn it off from the preferences or anywhere else in the UI. It should be able to be turned off though. I would file an idea on the idea exchange to add more options to the preferences.
If you wanted a (hacky) workaround, I created a bookmarklet you can use to disable the tag auto close on existing VF editors, and all plugins on new editors. If you still want things like gutter folding and matching tags on new editors, let me know and I can update the gist.
To use a bookmarklet, copy the code in the gist, add a new bookmark in you browser and paste the code as the URL. Then open the developer console in a tab so you access the bookmark. When the dev console loads, press the bookmark and the auto close tags should be disabled. Let me know if you have trouble with it. I only tested it in chrome.
