If you use an ESP8266 board, like a NodeMCU or Wemos D1, of course you can - those come with a built-in USB interface. For many other devices, there's tuya-convert - creates a special hotspot which "captures" the device, then flashes it via OTA for you. But Tuya already changed the firmware once to block this, and although the newest tuya-convert works again, there's no telling they won't do it again. Lately though Tuya devices have started using a Realtek RTL8710BN instead of the ESP8266 - those are completely incompatible boards, and to my knowledge there's nothing like Tasmota or ESPhome for them.
