Trying to use WTFast but I get this error.

So I've been trying to install WTFast but windows10's latest update has this new Driver Signature Enforcement where I can't run WTFast.
This is the error:

Then I tried to disable driver signature enforcement through CMD and it gave me this error:

So I tried to disable the secure boot policy and when I went into bios after going into UEFI Firmware Settings -> disable secure boot policy In the BIOS.... it was completely greyed out, I couldn't even disable it.

Could anyone help me out with this problem?

Edit: Specs are as follows:

CPU: i7 - 6700k
GPU: 1080 gtx
mobo: asus z170-k
Ram: 32gb 2400mhz ddr4 ram
