Which Diverge? Which year? Which tire? Which size?
Quickly looking at published specs for 2020 and 2021 Diverge models steering trail could be anywhere from 57mm to 69mm. Most would find 57mm to be quick handling. Some of the suggestions above will alter that a little, it will continue to be a quick bike. At 69mm that is one slow handling bike when on pavement. If you find a 69mm trail to be quick handling that is you. Or possibly it is because there is something wrong with the bike.
Impossible to to get started on solving this one until we know what you have.
