Arrange oven racks in the upper and lower thirds. Preheat the oven to 400°F. Spread the tater tots on one rimmed baking sheet and arrange the bacon in a single layer on another rimmed baking sheet. Bake both simultaneously, switching the positions of the pans halfway through, until the tots are hot and crunchy and the bacon is crisp. The bacon will be done in about 10 minutes and the tots in about 20 minutes. Drain the bacon on paper towels. Break into small bits. Arrange the tots on a serving platter in a single layer. While the tots and bacon bake, mix the cream cheese and parmesan cheese. Place the cream cheese mixture in a resealable plastic bag and snip a hole in one corner. Pipe a dot on to each tot, then top with the bacon, peppers, and chives.
