Realistically?

They can't. Not without a major change in American politics, which is unlikely given the amount of lobbying power that Israel has, and the grip that Evangelicals have on right-wing political power in the US. Anti-BDS (boycott, divestment, sanctions) laws intended to prevent people from protesting Israeli policies by cutting funding to the country have passed in nearly all states. We can see, with the way that current events are unfolding, that even expressing support for the Palestinian people is resulting in people being labelled as antisemitic.

(For reference - Evangelicals support Israel as a Jewish apartheid ethnostate because they believe that the Jews need to control Jerusalem and Israel in order for Jesus to return. It has nothing to do with Evangelicals liking Jews, which they mostly don't. If you don't want to believe that, I can certainly help you find sermons from megachurch pastors saying precisely that, but I generally try to avoid listening to that trash.)

We're very slowly starting to see that kind of change now, with the way that the youngest generations in the US as more supportive of the Palestinian people. But it's not likely to mean much, since by the time they have enough political power to do anything, Israel will have completed genocide.
