I think this TTGO has wifi connection embedded? 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, and it's not very usable without camera anyway.

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.

How did they remove the wifi chip? by the way, pi zero has no wifi at all.

What do you mean how? They simply desoldered the wifi chip from the board, and by the way newer version of Rpi zero devices does have wifi (only older version 1.3 doesn't have wifi), so better do your own research:

It's not a fucking pack of peanuts and you could just remove the bad ones. WIFI chip can be removed from an ESP 32 is the first time I have ever heard. It's probably not the easiest thing to do.

Yeah, it was also the first time in your life you ever heard about existence of Raspberry Pi Zero with wifi chip (that can also be removed manually)... I guess you must be smarter than me in this field  
Now let's get back on topic of Jade DIY.

new firmware 1.0.30 is now available for Jade!
the new version released today has the following new features:

• added new api calls 'get_registered_descriptors' and 'get_registered_descriptor' to enhance miniscript support
• menu option for network selection (mainnet/testnet) for stateless qr code users
• updated esp-idf base firmware to v5.1.3 (note: saved bluetooth bonds will need to be re-paired)

this miniscript-capable version can be flashed under the following link: https://jadefw.blockstream.com/upgrade/fwupgrade.html

Yep, it feels exactly like a seedsigner, how can I change that??

I guess you set it up using the Advanced Setup mode. The standard and assembled (non DIY) Jade has a beginner setup and advanced setup. The latter one creates a stateless signing device that you can use with SeedQRs. The beginner setup feature creates a standard wallet with the information stored on the device like with any other hardware wallet. You also need to set up a PIN. Like I said, this is for the normal Jade. I can only assume it's the same thing for the DIY variant. So, go through the beginner setup, not the advanced one.
