Greetings! I just got my Razer Blade 15 2018 (1070 version). In the process of setting up my system to dual boot to Win10 pro and Linux, I've noticed that there's no option in the BIOS to install your own keys to Secure Boot. I've found this post https://lukegb.com/posts/2016-11-11-secure-boot-shenanigans/ of someone who modified the BIOS of a RB stealth to enable those options. My questions are: 1. Does Razer provide an official modified BIOS to enable these options? 2. If not, is it absolutely certain that flashing a modified BIOS will void the warranty? Thanks!
