Applying jitter transform only on x

Is jitter transform not available in fastai2?
It was there in v1, but we cannot limit it to x only.Now if we can , then we are not having it.
Can anyone help me out with this?
If anyone knows how to limit it to x only in v1?

I am posting it on every forum that I can find, as I am very confused as fastai has got too many forums…
