Off switch for wandering trader

It would be great if you could add an off button in settings for wandering traders.  They are often in the way especially when multiples spawn.  It would be better if they are spawned as stationary mobs that spawn no less than 20 blocks from the player.  Or another way to manage them would be to allow fairly common objects to summon a wandering trader, perhaps a campfire that has meat placed on it to cook or something like that.  That way the wandering trader doesn't spawn in my structures or get in my way when building or steal my boat.
