Deactivate FireBeetle 2 ESP32-C6 charging led

I have a FireBeetle 2 ESP32-C6 powered with a AC-DC power source and with a ER18505 non-rechargeable battery via Vin pin, controlled with a relay. When I powered with USB or AC-DC power source, the charging led turns off, but when I powered with the battery, charging led turns on and keep fixed. I want the battery to last the most possible, so I want to deactivate this led. Is it possible? Thanks
