I highly doubt it, but yes it is possible.
Diamine Oxidase Enzyme degrades the histamines in the body. I’ve never known anyone to be allergic to it as it is in a mother’s placenta and breast milk.
Since the peanut allergy is a histamine response, it should help.

It helps reduce the allergy response but that may interfere with the desensitization process.
