Certainly, there is not the USB but i see that there are pins for GPIOs and GND 5V / 3v3 so i imagine that soldering pins are Okay to flash after which to electricity on :-)
I have two of these and take a look at to obtain tasmota working with the eth interface. As there is sort of no documentation obtainable it's a bit of trial and mistake to receive it likely.
