> What I'm asking is whether or not it is possible that there is a form of energy so far undiscovered [...] that can travel faster than light.

That is possible, but it looks very unlikely. And it's not related to entanglement.

> that registers at a quark or subquark level

That part doesn't make sense.

> Light is the current known standard by which to measure speed, but photons are comprised of "bundles" in the electromagnetic field being transferred super fast from one point in the field to another point in the field.

No, the speed of causality is a far more fundamental concept. Light travels at that speed, and we call it "speed of light" for historical reasons, but the speed limit is much more general than light.

> "The field" itself is what I would like to know more about and understand its role in energy transfer.

The electromagnetic field? That's again not a question about entanglement.

> Quarks are theoretical and considered so bc there isnt concrete physical evidence for them

Are you commenting from the 1950s? That's a time where such a statement would have been reasonable. We have studied quarks routinely for decades now.

> its entirely possible that there are even smaller units than quarks that are undetectable due to limits in current technology.

That's unlikely but we cannot fully rule it out. But again, this has nothing to do with anything else in your comment.
