Airgap supported for HA deployments?

Rancher 2.x

Hi,

I noticed on this link regarding tech preview for 2.0 that HA airgapped installs were not supported:

And on this link its implied that you can though doesn’t specify the HA type of install:

So my question is: Are HA Deployments (via RKE) supported via airgap?

Many Thanks,
Graeme
