How to wire unused LDO on ADP5052

I am using the four buck channels of ADP5052ACPZ-R7. The LDO (channel 5) will not be used.  I'm seeing conflicting information about wiring for this situation.

 

The Buck Designer tool shows the following connections when channel 5 is not used:

PVIN5 -> NC

VOUT5 -> NC

EN5 -> GND

FB5 -> NC

 

In this post BUCK and LDO which are not used in ADP5052 are safely set to disable. , @JonD suggests the following:

PVIN5 -> GND

VOUT5 -> GND

EN5 -> GND

FB5 -> GND

 

I don't see any information about unused channels in the datasheet.

 

What is the proper way to connect PVIN5, VOUT5, EN5, and FB5  when not using channel 5 LDO?
