Turning off the Wio Lite MG126 running on battery

I do have an adafruit feather. But I want to add bluetooth to my project. The feather have the option to powerdown the voltage converter via the enable pin.
And still have the option to to charge the battery. The same pin on the Wio Lite MG126 is an ground pin. But I can not find an enable pin to put to ground to disable the voltage regulator.

So how can i turn off the Wio Lite MG126 and still able to charge the Wio Lite MG126 via the USB-C port.
