How to make easing between animations constant instead of linear?

I am working on a game and i want to make it so when you play an animation, it instantly goes into position instead of easing into the position. I have no idea how to do this and i cant find any articles.

Enum.EasingStyle.Linear is constant, buddy! It does not accelerate or whatsoever.

Please take a look at this useful article Roblox has provided us: https://developer.roblox.com/en-us/api-reference/enum/EasingStyle

@Dehydrocapsaicin is correct, constant is the same as linear. I've not much experience with animation but what prevents you from just setting two poses with a a really short time, like a one frame gap in between? if even that's not enough, I don't think animations are what you're looking for.
