QEMU args generation order with libvirt

Hello, We are trying to bring up the Android VM with Libvirt, as part of this exercise it is advised to keep Replay Protected Memory Block (RPMB) device as the first virtio device in the QEMU arg list, as the secure storage daemon in Andriod side communicates with dev/vport0p1 for RPMB usage. Is there any way we can make a qemu commands generation in particular order with Libvirt XML ? Thanks, Shivakumar M
