separate irqs for network interfaces

Is it possible to have in proxmox vm two network interfaces on separate irq's?

now I have two interfaces but all are on the same irq.

cat /proc/interrupts
10: 36157195 0 0 0 IO-APIC-fasteoi virtio0, eth0, eth1

smp_affinity doesn't work so I try to divide network interfaces to separate irq's and allocate the CPU for each network card
