Place the eggs in a large pot in a single layer and cover with cold water by about 1 inch.
Bring to a rolling boil over medium-high heat, then remove from heat, cover, and let the eggs sit for 10–12 minutes.
Transfer the eggs immediately to an ice bath and cool for 5–10 minutes.
Peel the eggs, slice them lengthwise, and carefully remove the yolks into a mixing bowl. Arrange the egg whites on a serving platter.
Mash the egg yolks with a fork until crumbly. In a separate bowl, mash the avocados until smooth or slightly chunky.
Combine the mashed yolks and avocados with lime juice, mayonnaise, Greek yogurt, jalapeno, red onion, cilantro, garlic, cumin, salt, and black pepper. Mix until creamy and well blended.
Taste and adjust seasoning as needed.
Spoon or pipe the guacamole filling evenly into the egg white halves.
Garnish as desired and serve immediately or lightly chilled.
