You have two options, as outlined in this post from the forums: https://forums.evga.com/FindPost/2329153 To confirm,

Option 1 - Modify the EK block: if you modify ONLY the part of the block that is obstructing the pins, your warranty from us will not be voided.
 
Option 2 - Modify the EVGA PCB: We have received official confirmation that if you cut the test pins on the 980 KPE, your warranty on the card will remain intact.

Be careful if you do chose to modify your video card. If you should slip or cause any damage to the PCB besides just cutting these pins it would not be covered under warranty. Also please be sure to shut down your system and remove the card before attempting this. You do NOT want to do this when the card is plugged in or powered on.
 
Please also do not bend these pins, unless you can do it where they will not make contact with anything conductive and will not touch each other, as you do not want them to touch each other during use.
