His team almost definitely did, but Trump is notorious for being difficult to coach or prep with talking points, and is known for discarding 80%+ of his pre-written speeches and opting to go off the cuff instead. 

There is a guy named Mike Benz who used to be a speechwriter for trump (I believe he actually spoke at the conference this year himself) who has recounted stories of occasions when Trump would actually communicate positions that were at times directly antithetical to the positions articulated in the speeches he wrote.  

Ironically, one of the issues he was supposed to address in a pre-written speech was to expose and condemn Big Tech for partnering with NGOs and intelligence agencies to impose widespread censorship programs, but instead Trump winged the entire speech, and gave high praise to the tech industry saying "MAGA stands for Microsoft, Apple, Google, and Amazon".  This ultimately was weaponized against him and his voter base, and became a major determining factor in shaping the outcome of the 2020 election.
