You can use the /playsound command to play any sound from the 1.20 experimental datapack, without having it enabled. Just open any 1.19.3 world with cheats enabled and use the /playsound command for any camel, hanging sign, chiseled bookshelf, or bamboo block sound.

Any 1.20 sounds can be played with the /playsound command in vanilla 1.19.3 without the update_1_20 data pack enabled

Sounds, textures and models are client side, data packs are server side.
Whether you enable the data pack or not has no effect on clients, wanting it to change requires a fundemental change in data pack functionality, which is simply not worth it for a small thing like this, and goes against the whole point of client and server info being separated.
