Very thanks,I tried to apply your suggestions,as follows :

/mnt/./monta-fisso
sleep 2

UEFICODE=/usr/share/AAVMF/AAVMF32_CODE.fd
UEFIVARS=/usr/share/AAVMF/AAVMF32_VARS.fd
CD1=/mnt/fisso/OS/ISO/BSD/FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img
CD2=/mnt/fisso/OS/ISO/Linux/bookworm_mini_armhf.iso
DISK=/mnt/fisso/bhyve/img/FreeBSD/FreeBSD.img

qemu-system-arm \
-enable-kvm -serial stdio \
-m 512 -M virt -cpu cortex-a15 \
-drive if=pflash,format=raw,unit=0,file=$UEFICODE \
-drive if=pflash,format=raw,unit=1,file=$UEFIVARS \
-cdrom $CD2 \
-drive file=$DISK,format=raw \
-device virtio-net,netdev=net0,mac="52:54:00:12:34:55" \
-netdev type=user,id=net0 \
-device virtio-gpu-pci \
-usb -device nec-usb-xhci \
-device usb-kbd -device usb-mouse \
-device vmware-svga,id=video0,vgamem_mb=16

but the error is always there. Am I missing something ?
