ubuntu - Will enabling proprietary drivers on 17.04 install affect secureboot and bitlocker partitions?

I originally posted this on AskUbuntu but it was suggested to me in the comments that this might be a better place.


I have a Windows 10 Bitlocker partition that if I understand correctly requires SecureBoot to be enabled.


The BIOS in my Asus Z170-A motherboard does not give me the option to disable this, so I cannot test if it will boot without it.


I have attempted to install Ubuntu 17.04 alongside windows and the installer froze with nouveau sched_error messages presumably because of my graphics card, a 1080 Ti.


By adding nomodeset to the boot options I was able to get the disk to install. I did not select "install proprietary drivers" because the prompt warned that it would disable secure boot, which I feared would permanently prevent me from booting into Windows 10.


The install was successful, but presented me with a purple screen on launch, until I again added nomodeset to the boot options.


I was able to log in, and the system worked fine, but at low resolution with massive screen tearing.


I ended up deleting the partition, and want to try again from scratch.


If I enable the proprietary drivers, will it effect my ability to boot into a bitlocker encrypted drive?


Will it fix my graphical issues?
