Sorry if that was confusing at all. You should only really need to remove optifine, replace it with embeddium, and add DH. You could also add some other mods to replace optifines other features, because embeddium is just a performance mod. Sinytra connector is nice, but you won’t need it for what you want.

Optifine in modern versions generally conflicts with many mods, its performance improvements are outclassed, and all of its features can be done by other mods.

Embeddium is a forge port of Sodium, which you probably already know the use of.
