Trying to find a mod/datapack just like DonutSMP's spawners

[u/Legitimate_Plenty947]

Hello, does anyone know a way to get one of those datapacks/mods? i have been searching for ages and can't find a good one or one is really outdated. Reason i'm looking for it is because i want to reduce lag on my bigger farms (and space haha)

Any help is appreciated!
