You’re looking for WiFi Component — ESPHome - power_save_mode: HIGH
I don’t think that turns Wifi off, though.

In Modem-sleep mode, ESP8266 will close the Wi-Fi module circuit between the two DTIM
Beacon intervals in order to save power. ESP8266 will be automatically woken up before
the next Beacon arrival. The sleep time is decided by the DTIM Beacon interval time of the
router. During sleep, ESP8266 can stay connected to the Wi-Fi and receive the interactive
information from a mobile phone or server.
