Can a regulator be used instead of gpio in other board case?
No, not to my knowledge.
Hm.. plz check it out again. the gpio pin is specific to board, and the the gpio be used as power source trigger could be replaced with a regulator according to board design. So you should consider all possibilities even though there are no other cases yet: other board could use a regulator instead.
Take a look at the data sheet, it is publicly available.
PD_N is not a power supply input, so modelling it as a regulator makes no sense:
"If PD_N is LOW, then the device is in Deep power-down completely, even if supply rail is ON; for the device to be able to operate, the PD_N pin must be HIGH."
