If you are pressure canning, changing ingredients is not an issue since pressure canning does not rely on acidity to make
the product safe.
If pressure canning, you don't even need any acidity.
But i want to make sure it is pressure canning in a pressure cooker and NOT a boiling water bath. You said pressure cooking, i am mentioning this so others reading this may recognize there is a difference between pressure canning and boiling water bath.
