Hardware Buy a new switch console

[cernusco]

Hi,
I would like to buy a new console and then use one of the dongle to play backup games. Is there any way to know (in a closed box) if the switch is vulnerable or patched? What do you suggest for the purchase? A used switch?
Thanks

The serial number is exposed on the box. There are lists with serial numbers that should be exploitable.
