You can't ...
But you can disable unuse port like serial ports and hoping it will
free up an IRQ.

Also, depending on what your problem is, you may want to try physically
moving the PCI cards to different slots, and you may find a combination
that works. Often the motherboard manual will tell you which slots share
an IRQ with another slot or motherboard resource like USB/mouse/IDE
controller, etc. - this may give you hints on which slots to avoid.

If you use a USB mouse, often you can disable the PS/2 mouse IRQ (12),
which frees it up for other use.
