TPS63050 Enable Pin Pull-down Resistor
Since the leakage on that pin is so low (high impedance), you risk the pin being susceptible to interference with such a high value resistor.  Something more reasonable like 10 kΩ would probably be better, but still not needed.

This pin is usually just shorted to the power rail.  The static current draw will be next to nothing (typically 0.01 µA).
