This was ruled by the Supreme Court, an Asian man (Chinese, I think) in favor of birthright citizenship, in the 19th century.
Not sure an EO can undo it.
I think a law would need to be passed by congress.
Then, "Under the Jurisdiction of" would need to have a 2nd look by the courts.
Unfortunately, I would not be too hopeful that is would reach the desired outcome.
Will we never know until it is tried, and I do not think this current congress has the make up or the will to do such a thing.
