Prismarine has a very slight animation where it turns from blue to green and then back again within a span of about a minute.
I'm not sure if this would increase performance at all, but here is more info about it: https://minecraft.fandom.com/wiki/Prismarine#Usage

Maybe the mod could disable this.

This mod is supposed to not remove animations from stuff for performance, e.g. chests. If you use sodium, you can use a mod called Sodium Extra to disable certain animations, including block animations from stuff like prismarine, sea lanterns, magma blocks and crimson/warped stems.
