You are misguided, these are not the gateways you seek.
The TTI stack is software, ESP is hardware - it’s the software on the device that makes it compatible with LoRaWAN.
Not without stringing at least 8 together and writing code to co-ordinate their efforts and somehow sort out the channel activity detect. Which would cost more in hardware alone than an actual gateway. Even two ESP32 modules cost about the same as a TTIG.
No one here can help, walk away whilst your soul is clean.
