You can do it but you indeed risk bricking your card.
 
If you kill your card updating the bios you will be the only one responsible and the warranty will be voided. You have been warned (again).
 
That beeing said, thought even with a failed flashed bios you can also try to flash the original one using another video card for displaying with the bricked card plugged in. However this does not mean that it's a solution that will allow to unbrick a card every time.
 
What do you mean by "the new bios doesn't seem to take"? What happens exactly? What commands did you use to flash the card? What are the exact steps you took?
 
Also 40°C doesn't seem that low with watercooling. My 1080Ti watercooled runs at 35°C max at 120% TDP. What watercooling system do you have (waterblock, radiator)? Are you sure it is installed properly?
 
Also if you really want to unlock your card, the best bios is the asus strix 1080Ti XOC bios which has no power limit and voltage unlocked until 1.2v. The FTW3 bios is not better than the XOC bios. Also do not try to use the XOC bios on aircooling as it could fry your card because it would run too hot.
 
But you need to know that even if you might get higher clocks using another bios with higher TDP/vcore, a lot of people are reporting lower performance score on 3DMark even with faster clocks on another bios. So a lot of them went back to their original bios because even with lower clocks they had better performance with it.
 
Once again, i am not responsible if you kill your card trying to flash it.

Do you run an elevated command prompt? Do you use the latest version of nvflash? Did you check if your downloaded bios and nvflash files are unlocked on windows when you right click -> properties on them?
 
Did you try to reinstall the drivers after the reboot and flash (clean install)?
 
Try flashing with -L log.txt -6 biosname.rom
 
This will generate a log.txt file. Post it here please.
 
If it still doesn't work, you can try to use nvflash 5.370 instead of the newest version.

Glad to hear it :)
 
So what did the trick? What results do you get with the new bios? ;)
 
My MSI 1080Ti Sea Hawk EK X (couldn't get my hands on a kingpin in france but i wish i could have :D ) can run 2100 Mhz @ 1.093v  with the stock bios at 35°C. When i flashed the Asus Strix OC bios that has no power limit and 1.2v i could reach 2160 Mhz at 40°C but my results on 3DMark were the same than at 2100 Mhz... So i went back to the original bios ;)

While were on the subject matter. Is there a newer bios version for the EVGA 1080 Ti FTW3? I'm currently on BIOS Version: 86.02.39.00.90

What are you using for cooling?
 
I am on water using 86.02.39.01.91 on my FTW3
 
Bios from this thread .. https://forums.evga.com/FindPost/2693145

 
I'm using the stock cooling that comes with the card. I see your bios version is for the water cooling version of the card. Wouldn't that toast my card if I flashed it with that bios version?

WOW! Is there a change log on what's new with the bios version: 86.02.39.01.91 I downloaded the file and extracted it to the desktop. It shows a primary and secondary. I'm running in SLI. Do I have to flash each card separately to do perform the firmware update?
 

Primary = Master
Seconday = Slave
 
I'd recommend flashing each card separately with the other completely removed from the system.

Well I have tried the xoc bios and I still can’t run more than 1.08v. This will only allow me to clock to 2075. Very annoying as the temps are so cool.
