TrueNAS on Lockerstor Gen3

[Enquiries]

Purchased new AS6806T. It has no HDMI port. Is it still possible to install TrueNAS on this new Gen3 Lockerstor NAS, and if so, could you point me in the right direction. I've read/watched your guide to installing TrueNAS on Asustor, but I fail the requirement for connecting a monitor as far as I can tell.
Thanks!
BTW, I joined your 'inner circle', but not sure how best to use it for a question like this
