How deep can a blue whale fart?

At some depth, would the water pressure be so high that it would be impossible to let one rip? Like are there whales out there swimming around like a mile down and suddenly they gotta fart, and they just feel uncomfortable while holding it in until they can swim up to like 100 fathoms?

Whales do fart and they can still pass gas under water. Unlike submarines where the inside pressure remains lower than the environment, whales, divers, and marine life have the same pressure inside their body as the outside, otherwise they would be crushed. So the volume of gas for the whale to fart would decrease as the dive and the pressure would increase to match the surroundings.
