Is this possible with the ESP libraries?
It seems to be possible to set the power from 0 to 20.5 according to some comments such as on: https://github.com/esp8266/Arduino/issues/764 and https://github.com/esp8266/Arduino/blob/41074245a8d3029270622a8b489d53fdfedb2a22/libraries/ESP8266WiFi/src/ESP8266WiFiGeneric.cpp#L169-L179
/* set the output power of WiFi
The datasheet for the AT command set also has power control support in 0.25 db steps, 0 to 20.5 :

For a short range point to point WiFi serial communication, it would be nice to be able to reduce the Tx power. It would also reduce power consumption on battery.
