VFIO_pci wont bind to graphics card

I've had little success trying to set the graphics card drivers to vfio_pci and was wondering if anyone could potentially help me.
I've turned on all the virtualization settings in the bios
My rig is:

Kernel: 5.0.7-arch1-1-ARCH
OS: Arch Linux x86_64
MB: Fatal1ty Z97 Killer
CPU: Intel i5-4690 (4) @ 3.900GHz
GPU: NVIDIA GeForce GTX 1060 6GB
Host GPU: Intel HD Graphics
Memory: 15797MiB

I've enabled IOMMU and it shows up as enabled with dmesg | grep -e DMAR -e IOMMU
The graphics card I want to passthrough is in a group that I don't mind passing all through to the vm
e.g
IOMMU Group 1 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller [8086:0c01] (rev 06)
IOMMU Group 1 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] [10de:1c03] (rev a1)
IOMMU Group 1 01:00.1 Audio device [0403]: NVIDIA Corporation GP106 High Definition Audio Controller [10de:10f1] (rev a1)

I've followed the wiki for all the instructions
/etc/modprobe.d/vfio.conf

options vfio-pci ids=10de:1c03,10de:10f1

And in
/etc/mkinitcpio.conf

MODULES=(vfio_pci vfio vfio_iommu_type1 vfio_virqfd)

HOOKS=(base udev autodetect modconf block filesystems keyboard fsck)

I regenerated the initramfs configuration
and I also placed vfio-pci ids=10de:1c03,10de:10f1 in kernal parameters
but the vfio_pci still wont bind and nouveau still takes them

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] [10de:1c03] (rev a1)
    Subsystem: eVga.com. Corp. GP106 [GeForce GTX 1060 6GB] [3842:6267]
    Kernel driver in use: nouveau
    Kernel modules: nouveau
01:00.1 Audio device [0403]: NVIDIA Corporation GP106 High Definition Audio Controller [10de:10f1] (rev a1)
    Subsystem: eVga.com. Corp. GP106 High Definition Audio Controller [3842:6267]
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel

Blacklisting nouveau just forces no drivers to take its place.

My original thought process was that im changes aren't being applied on boot, but I don't know where to look to confirm that or fix that. or maybe I haven't applied the initramfs properly or set up GRUB properly to deal with new changes.
Any advice would be greatly appreciated, and comment if you need additional info

Re: VFIO_pci wont bind to graphics card

What happens if you try to manually bind/unbind according to the special procedures section here?
