A5000,need to execute the shell command /usr/lib/nvidia/sriov-manage -e 0000:3b:00.0,when I reboot the machine

I change the mode as below:
./displaymodeselector --gpumode physical_display_disabled
./displaymodeselector --gpumode compute --auto
and then exec the command:
/usr/lib/nvidia/sriov-manage -e 0000:3b:00.0
the directory /sys/class/mdev_bus is correct;
but I found a serious problem,when I reboot the machine,I have to execute the shell command /usr/lib/nvidia/sriov-manage -e 0000:3b:00.0 again,it is unreasonable;because some vGPUs(8G or 16G .and the total is 24G) maybe adapter to VMs;
Some ideas?Can you help me?
