Android standalone LAN multiplayer. Possible?

I have an Meta  MP application, registered via Meta dashboard, working via EOS. It works. (I mean, i m familiar with this workflow).

I can make Unreal app, that connects players in LAN (without internet).

So, the question is:

Is it possible, to connect 2 (or more) Quest 3 (standalone app)  users WITHOUT internet, via LAN? (I'm not meaning Colocation,MR capability, just standard network connection). Or every MP possibilities require initial connection to internet ( Meta), and approving via dashboard for security reasons?

If "Yes" - how to do this? How to realize this workflow?
