To spawn the Ender Dragon in the Overworld without mods, you need to use the command "/summon ender_dragon" in the chat. Make sure you have cheats enabled in your world settings. You can also specify coordinates to spawn it at a specific location by adding those coordinates after the command. Keep in mind that this action is not part of standard gameplay, as the Ender Dragon is typically found in the End dimension.
There are a few mods that can do so, But they can not be spawned in vanilla minecraft.
You can't unless you use mods.
