I recommend using your instant pot. I have a foodi (similar, different brand) and no longer hard boil eggs any other way.
Put eggs on a rack with a cup or so of water under them. I cook up to a dozen, but more can fit.
Set to pressure cook on high for 4 minutes.
Allow pressure to reduce naturally for 4 minutes.
Vent, remove eggs to cold water bath.
Shells will fall off easily.
