Place the trivet in the Instant Pot and pour in 1 cup of water. Place a parchment round on the trivet and lay the salmon on the parchment (it’s okay if the fillets rest on each other).
Lightly brush coconut aminos on the top of each salmon fillet.
Secure the lid, move the valve to the sealing position, and hit Manual or Pressure Cook on High Pressure for 4 minutes. Quick release when done.
Meanwhile, make the pesto by combining all the ingredients in a food processor or blender and pureeing until it reaches the consistency you desire.
When done cooking, carefully remove the trivet and rest the salmon on a plate. Brush the pesto on each fillet and serve.
