How do I check my UEFI version using Ubuntu?

I want to determine if a friend's PC is UEFI v.2+, that is UEFI version 2 or higher in order to make thumbdrive for installing Windows OS on a new SSD. I am presently running Xubuntu 18.04 LTS as a live boot with persistence from a USB. Other than that the PC is presently inoperable with a new SSD that is blank and awaiting an OS installation.

This website https://www.pcsuggest.com/check-bios-uefi-motherboard-info-in-linux/ touts the use of the dmidecode terminal command with various filters as an approach.

Does anybody know for sure?

Thanks,

A.
