Yes, of course. External control can be done over ethernet / Wifi (MQTT or whatever), or maybe even RS485 or I2C.
"Manual Control" by buttons etc is mostly not needed for an interface only product.
Think of an MOSFET output only board as an "EPS32 programmable output interface". Like the KC868-AI is for inputs.
It's also good for extensions. That's why I would not start below 32 channels.
