Minecraft without Server - Are there multiple end-settlements or just one?

I'm just trying to build lots of Shulker boxes and have seldom found a new Shulker in the only final settlement: are there any more permanent settlements and how do I find them from version 13.2?

Server and singleplayer are the same without plugins and mods!

Um, yes, - I was now in the question of whether there are several final settlements or only one… (?)

There are endless you have asked without a server! And if there were only one on servers, how would the other players get something? So server and single player are the same and that's why there are so many! Just have to search!

Yes, - that reminds me, - super- thank you! I'm already there:-)
