Yes probably, by replicating the code included in display hat mini library!

You do not need the library. Just control the ACT LED on pin 47.

See for example lines in https://github.com/Wikinaut/pinetradio/blob/main/pinetradio.py (look for ACT, which stands for activity LED.).

PI system use of the ACT-LED must be disabled. You can use this service https://github.com/Wikinaut/pinetradio/blob/main/disable-led.service and run sudo systemctl enable disable-led once.
