The Module have a dedicated VREF pad, but I guess it's only for bypass cap use?

   

If I import a battery monitor example it wastes a pin, example P3.3 that it calls Vref.

   

What is the difference between VREF and Vref?

   

I have access to LDO 3.3V voltage, would this help getting around wasting a pin?
​The 0.03Vdrop LDO is for a subsystem, so I do plan to run the BLE directly from li-po battery
and have it turn off the ldo when subsystem is sleeping.
