No. This is why I have mods. Live Another Life, never go past the Horn of Jurgen quest, then very few dragon spawns. It’s the quest with Delphine where Alduin raises the dragon from the dragon grave that really spawns the hobillion dragons. So, if you don’t care about the main quest, just don’t go past giving the horn to the Greybeards.
