My power % isn't as high as I'd like it, 66-70%, and my temp is steady ~55C under extreme stress @2000mhz clock speed. I'd like to be able to increase my Voltage higher than 1.093V, which is at 100% in EVGA precision X right now. My question is how would I go about doing this overvolt without having the option to do it on Precision X?

There isn't really a hard limit to voltage on the GTX 1080 like people though. BUT, it provides no benefit and actually decreases performance. Even overvolting last gens 980s and others provided no benefit, only drawbacks.

Then how come I've been seeing performance increases by increasing my Voltage so far? How else would I get the GPU to hit 100% power usage? Its stuck at 66% and won't go further than that, limiting my FPS in games.

How are you increasing your voltage exactly?

I believe you are talking about increasing your temp target, which is exactly what you need to do. If your usage is at 66% because your GPU is cutting power due to the thermal target you have set... That isn't overvolting.

Its definitely not my Temp target at my temp target is at 92C and I'm barely hitting 55 under load. The only increase I've seen in performance so far is by increasing my Voltage through EVGA Precision X which I had a picture of here:https://gyazo.com/81d4404adb6f2b13b025e70f001a4d39
How can I access the gtx 1080 BIOS as to increase the number further? Preferably to about 1.2V

Exactly - you aren't increasing your voltage, nor does it help. Your just manipulating an offset, it has an effect of allowing more voltage - but not beyond the cards settings.. Your GPU isn't under load in any of the pictures.

Your problem, really, is this:

Your card isn't being utilized at 100%. That isn't a reason to increase voltage at all!
A reason to increase voltage would be "My card is at 100% usage, but crashes, it needs more power for stability" That is a reason to overvolt!

"my card isn't being fully utilized"
Things to do about this:
Temps aren't a problem, as you have pointed out.
So...

What CPU do you have? sounds like a possible bottleneck!

You say Overvolting doesn't help FPS but after I increased Voltage, without touching any other setting, my FPS went up from 55 to almost 80 in BF1. While this is a nice increase it doesn't hold a candle to some guy who had 110 FPS with the same GPU but he had a better CPU. I'm currently using a 3770k with 1600 ddr3 ram, could these suckers be the culprits?

Take a look at this link, https://gyazo.com/81d4404adb6f2b13b025e70f001a4d39
I used EVGA Precision X and turned the Voltage up with the red/yellow slider on the left hand side
Worked like a charm because for some odd reason my voltage previously was just stuck at about 880V now its ~1090V
The only issue now is that the GPU power is still not at 100%, I really want to make full use of this card not just 70% of it.
