If you create a Minecraft server in 23w04a-23w06a and enable the initial update_1_20 datapack, camels spawn, chiseled bookshelves can be crafted, etc. However, even though they are in the creative inventory, smithing templates do not spawn naturally in any chests or from killing elder guardians. This makes it impossible to upgrade to netherite/customize your armor in survival on a server.

No, the issue isn't that you can't upgrade, the issue is that the trims don't generate in loot chests.
Did you create your world with the 1.20 experiment enabled (MC-256552)?
Edit: Just want to make sure, because on a server it's not as straightforward as just enabling a data pack.
I just tested this on a local snapshot server, after creating the world with the update_1_20 initial pack, the first shipwreck chest I opened contained two templates.
I did create my world with it yes. It might be working for you because yours is a local server. I'm using bisecthosting, so I don't know if its just them or all online servers.
Does MC-259470 describe your issue?
