This is a variation of the Instant Pot Breakfast Bites found here. I made this in a 6.5" pan, but you can use any pan that fits in your Instant Pot. If you use a larger pan you may need to double the recipe.
In the attached pictures you might not notice but I forgot the chopped bell peppers. Makes all the difference!

Spray the pan with the cooking spray. Set aside.
Prepare the potatoes per the instructions on the package. I like to get mine pretty crispy on the outside.

METHOD 1:

• While the potatoes are cooking, add all ingredients, except the water and the cheese for the top, into a bowl and mix with a mixer until the mixture is light and airy and fully incorporated.
• Mixing this enough to get it fluffy is important.
• Put the fried potatoes into the bottom of the pan, and then pour in the egg mixture.
• Sprinkle the remaining cheese on top.

METHOD 2:

• While the potatoes are cooking, place the eggs, cream, green onions or chives, bell peppers, and salt and pepper, into a bowl and mix with a mixer until the mixture is light and airy and fully incorporated.
• Mixing this enough to get it fluffy is important.
• Put the fried potatoes into the bottom of the pan, top this with a layer of the 7 sausage patties, and then pour in the half of the egg mixture.
• Then make a layer with the 2/3 cup grated cheese and add the remaining egg mixture.
• Sprinkle the remaining cheese on top.

For either method, pour water into the inner stainless liner of the pot.
Then set the pan on a trivet and very carefully set it in the pot.
I loosely covered it with foil. 
Close the lid of the pot and set the steam release knob to the Sealing position.
Press the Pressure Cook or Manual button (or dial) then set for 10 minutes.
The pot will take a few minutes to come to pressure.
When the cook cycle is finished, let the pot sit for 8 minute Natural Release.
Then open the steam release valve to release the remaining pressure until the pin in the lid drops down.
Open the lid.
Carefully remove the pan using the trivet handles. 
Set aside to rest for about 4 minutes.
It may be puffed up quite a bit, but it will go back down.
Slice into wedges and enjoy. Also can be frozen.
