In linux kernel since version 5.1 (release Date: 2019-05-05)  
WireGuard is a secure, fast, and easy to use replacement for IPSec
that uses modern cryptography and clever networking tricks. It's
designed to be fairly general purpose and abstract enough to fit most
use cases, while at the same time remaining extremely simple to
configure. See www.wireguard.com for more info.

It's safe to say Y or M here, as the driver is very lightweight and
is only in use when an administrator chooses to add an interface.
