Are there actual things Trump could do to "crash" the economy?

Sorry if this is a dumb question, but I’ve been reading a lot about recessions, and I keep seeing mixed opinions on how much power the president actually has to cause or prevent one. Some economists seem to think that when a recession is on the way, there’s not much a president can do in the short term to stop it or make it happen.

I get that things like tariffs can make certain goods more expensive, but if a president went really extreme with something like that, could it actually trigger a recession? Or is the president’s influence on the economy not really strong enough to push the market into a downturn like that?
