How to disable 'display adapter' in ubuntu?
In windows, it was possible to disable the necessary device through the device manager:

Answer 1

1) Run lspci, find the desired device in the output, look at its PCI address in the first column.
For example (I'm experimenting with a FireWire controller):

$ lspci
...
0d:00.3 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 PCIe IEEE 1394 Controller (rev 04)
...

2) Disable the device at the PCI bus level:

$ echo 1 | sudo tee /sys/bus/pci/devices/0000\:0d\:00.3/remove
1

Of course, this only works until a reboot.

Answer 2

try this:
1) sudo lsmod - list of devices
2) sudo modprobe -r device - disable the required device.
