All the juries in Federal prosecutions of Jan 6th defendants so far have found them guilty. I think very few people in the jury pools actually know about jury nullification. Even if they did support Trump, when the evidence is there and 11 other jurors vote guilty every time they vote, they fold and go along with the others. It's perjury to lie to get on a jury.

There might also be some fear about "giving aid or comfort" to insurrectionists, which carries a 10 year maximum sentence. It would take some cajones to commit the crime the defendants have been charged with! How do you benefit from that?

Educating anyone benefits everyone.
