From what I can see, anything regarding that only exists with 15.X beta firmware. The little I can see, its revolving around DNS, not sure about site to site stuff. I'll upgrade my lab MX to see what I can see
@EduardoML I just had a look at this, and it looks like it's not gonna work: first of all, you'll have to create an IPSec Profile for a non-Meraki peer.
Having a look at that, it only supports DH-groups up to 5. The documentation provided by Umbrella (https://docs.umbrella.com/deployment-umbrella/v1.0.6/docs/supported-ipsec-parameters) requires DH-groups 14, 15 or 19. Strangely enough, the MX I tested was running the latest beta 15.15, so it should be possible to have that in place. Perhaps you'd have to get in touch with Meraki support to have that added to your dashboard.
