You can definitely increase vertical but it takes an insane amount of work.
Part of it is genetic, since calves are generally dived into two categories, fast twich or sliw twitch muscle fibers. Well a third as well I suppose, which would be a blend of both equally.
That being said, vertical jump starts in the lower back, through the quads and finishes with calves.
Any type of jump/squat variations will help, deadlifts for sure as well as core work.
Calves is just a fuckin guessing game. Usually leaning towards super high volume and or super heavy weight.
Remember your calves are trained WAY fuckin more than any other body part(walking) so they can take alot of abuse and are stubborn as fuck to respond
My advice would be to look for videos on jumping mechanics(how to physically elevate, leave those doods working on engines alone) and train the muscles involved in the actual mechanics
