Under linux, you could use "modprobe" to add kvm modules in a script calling qemu and then use modprobe to remove them when exiting qemu. if you are are running multiple qemu's i suspect modprobe won't remove a currently used module, but take care here. maybe also install some watchdog to monitor qemu usage and remove (in case qemu crashed or was hard killed).

I have a question about activation of kvm.

Is there any way to enable/disable kvm at qemu runtime?

It should be useful for sandbox tools like DECAF or TEMU,
because some malware use VT-x information to detect these.

Best regards.
