[Hi10Go] Some question

Hi all. I bought a Hi10Go and while it comes to home, im checking several things reading the fórums. Because there is not an specific forum for hi10go is difficult to find info.

Main doubt is about original image of the installation. If I want to install Linux, and/or try a dual boot or something like that, and want to restore original image,are drivers and restoration files available somewhere?

I readed for windows 11 upgrade is better to backup drivers and clean install windows 11 (and what about the license?). I bought a usbc hub. Can I use a pendrive there for this, right? On the other side, I will not have the original keyboard, and probably my BT keyboard will not work to access bios, and so on, but, will work a usb keyboard connected to the hub?
