Disable/Turn Off Dedicated Graphics Card In Fedora Server

A bit of background before the real query,

I was using Fedora 26 (Workstation edition) as a home server along with KVM (using Virt-Manager) for further hosting other instances of Ubuntu Server and one instance of Windows 7. It all worked just fine till the time I realized there's more to be achieve by getting rid of desktop environment totally considering the only thing I used GUI was for managing virtual machines (which I believe can be done remotely and/or using command line). Another reason was to turn off the nasty dedicated graphics card (Nvidia 525M) by going into the Settings -> Display and turning off the second monitor (which resulted in Graphics card not being used at all!) on Dell Inspiron 15R (N5110).

On to the real question, I decided to use Fedora 26 (Server edition) and got it installed without any hiccups except for I cannot find a way to disable the dedicated graphics card. Looking through the threads over here and SO in general made me try things like disable noveau in grub, using xrandr (lxrandr), echoing OFF in vgaswitchroo, etc but none of the methods worked so far.

I understand its a decade old machine but it would be great if there was a simpler way to simple turn off the graphics card once in for all!

Thanks for your time :)

Why do you exactly want to turn off the graphics card? The easiest way, if not used at all, would certainly be yanking it out of the computer physically :-)

Because a. there's no need for it, and b. the system gets insanely hot to the point of shutting down. I haven't really looked into pulling out the card physically but I believe it is sort of soldered to the motherboard.
