Calling Additional Scripts from Arduino-Cli when uploading to a board

I have a Raspberry Pi connected to an Arduino Mini that it normally communicates with over I2C. But I'd also like to be able to reflash the Mini with new code using Arduino-Cli from the Raspberry Pi (kinda rhymes!). This would involve connecting the Raspberry Pi's GPIO serial port to the Arduino's serial port. Additionally, the Arduino Mini requires a manual reset to be applied before its code can be reflashed, which is something the Raspberry Pi can do by toggling a GPIO pin attached to the Mini's reset line. I can do this with a simple Python script. The question is: is there a way for Arduino-Cli to call additional scripts as part of the upload command?
