The image below shows a tunnel interface configured with an IPv6-EUI address and the show interface command does not exhibit the configured IPv6 address. This IPv6 is not available in the system.

Tunnel Interfaces also do not generate/configure a Link-Local IPv6. It looks like Tunnel interfaces do not have any MAC Address associated to it.

In VyOS 1.3-rolling-202008170118 the interfaces do not generate/get the configured IPv6-EUI Address, as in the image:

I will take at look if I can implement a short fix to generate IPv6 Link Local addresses on wireguard interfaces.
