While tariffs on coffee do not incentivize coffee growing in US they do two things that are very beneficial for US economy
1) People replace coffee with hot cider, infusion tea or some other local substitute good.
2) Tariff on coffee as set up by Trump incentivize coffee producing countries to buy US goods whether it’s oil or cars to make trade balance more equal.
The only question is the scale of above but tariff on coffee is unquestionably help US producers.
Yes, tarifs can change behavior. I'm not sure that's the goal here, and I'm not convinced there's a local alternative to coffee (at the scale Americans drink coffee.)

Countries don't buy goods, people do. Apparently insulting Canada didn't make them decide to consume more made-in-America goods. I'm not sure that random acts of insulting leads yo the effects you are proposing.
