Question Can I use Jetsons TX2 as a normal single board?

I don't see why not, if you don't mind using a non-standard version of linux (which means limited support), and learning a whole new computing environment.

The fact that you ask that question on this forum means to me that your level of expertise is probably a little shy of what is needed.

That all said, what you propose is a major challenge with only a modicum of reward. What you will get is a lot of knowledge about this board. Contact the manufacturer and request a full set of documentation and an OS download (plus instructions on how to install and run the OS)
