You would have to dissemble the satellites and check with a multi-meter if the pin in question is connected to the ground side of the PCB.
The ground is the traces connected to the neg battery side or brown/black lead of the servos.
The chip has a feature called PMU. Look in below doc and look at description of pin 37.
On my units the pin 36 was connected to GND as dictated by the datasheet.
So it could just be a matter of soldering the 2 pins together....

In addition, the CYRF6936 IC has a Power Management Unit
(PMU), which enables direct connection of the device to any
battery voltage in the range 1.8 V to 3.6 V. The PMU conditions
the battery voltage to provide the supply voltages required by the
device, and may supply external devices.
