I don't doubt that the home team may make changes to their advantage, but I don't think the broadcasters would particularly like it if the pitch absolutely destroyed any chance at good entertainment. In International Cricket, the equivalent would be preparing the pitch to the home team's strengths (which went horribly wrong for India, the home team, in the 2023 World Cup Final, which was as drab as they come).
