Edge Impulse Developer with my own hardware

We are considering using Edge Impulse for keyword spotting on custom hardware that uses and ESP32 chip but we would not like to upgrade to the enterprise plan.

When I go to build the model and select custom hardware, it says that is a feature only available to enterprise plans. Is it possible to build it to one of the supported hardwares (the ESP-EYE for example) and modify the code to be compatible with our custom hardware?
