Depends on what kind of zealot we’re talking about.
*Not a zealot against LGBTQ+ people, abortion, or other “culture war” issues.
However, he’s very willing to give the zealots among his supporters what they want. Would Trump propose or call for a bill to make abortion illegal nationally? No, I actually believe him when he says he favors the state-by-state approach. But I’d also be surprised if he didn’t sign such a bill if it came to him through the efforts of others.
*Zealot on being anti-immigrant. It’s his original and “best” political argument, his first and last resort as a scoundrel.
In his stupidity, he swallows various idiotic theories on why 14th-Amendment citizenship-by-birth isn’t what it is. I don’t believe the Supreme Court, even as composed now, is dumb enough to adopt any of the ridiculously crabbed interpretations he subscribes to because they’d bring uncertainty on citizenship to way more people than the target races/ethnicities.
But that ain’t going to stop increased deportation efforts in which citizens will be caught in the dragnet, because Trump will put people in charge who care more about the color of someone’s skin or the languages they speak than whether their papers are in order, who’ll sacrifice “efficiency” for precision. A “streamlined” process will be put in place, and the Supremes will likely uphold it so long as it has some kind of relief valve however weak. Some wrongly-detained people with money or other resources (public sympathy from neighbors or social media) will indeed manage to obtain release in non-MAGA courts, which Trumpists will point to as “proof” that the new system works, but many of the poorest will be deported though born in East L.A. (or Pilsen, or Spanish Harlem).
*Zealot on opposing any kind of response to climate change other than “burn, baby, burn!” One of his first acts in his first term was getting the U.S. out of the climate accords. He spent his entire term striving as much as the laws and political opposition would allow to open public lands to intensive resource extraction.
The ongoing closing of coal-fired power plants and the increased economic viability of wind and solar power? The fact that the oil companies aren’t clamoring for more places to extract oil? The economic benefits of tourism to public lands? Trump, like shingles, doesn’t care. 
Trump believes prosperity itself comes from the unlimited burning of coal and oil; a fetish, in the non-sexual sense. Moreover, he’s demonstrated a firm belief that any public land not dedicated to intensive resource extraction is being wasted. That’s one of the kinds of “waste and inefficiency” DOGE is there to go after.
