Can you please clarify what to do with the UVLO pin on MAX17613A?

The UVLO pin should not be left floating.

If the user prefers to not use the UVLO function through the UVLO pin, and plans to use the “Internal Undervoltage Trip Level” instead, then the UVLO pin may be pulled up to VIN through a resistor.  Note that this resistor (2.2MΩ) is helpful and needed when the input voltage goes negative with respect to GND.
