I think this TTGO has wifi connection embedded? Huh

How can anybody use this to store your private keys?

Wi-fi is disabled in settings and I know people who are removing wifi chips from this device, they also did the same with RaspberyPi zero.
Than again, nobody is really going to use cheap TTGO device to store keys there, it's just a proof of concept.

I wish there was a DIY device that by default has no wifi at all...

Sure there are, Seedsigner aka Raspberry Pi zero v1.3, Krux aka M5StickV K210 or Maix Amigo, they are all airgapped devices without wifi.
