Send characteristics to Bluetooth LE device - gatttool like tool? - HassOS on NUC

I would like to send some characteristics to BLE device but I cannot install gatttool on HassOS. Is there any similar tool I can use? bluetoothctl is working but afaik, it cannot be used to write gatt characteristics.

I am using gatttool successfully on my standalone RPi with NodeRed but now I would like to use BT on my NUC with HassOS installed.

Thank you.
