I'm using imx8mq evk.

How can I change the mode of vpu of imx8mq to overdrive mode? I know it's not recommended, but I want to change the mode of operation of vpu for the test.

If I print out the gpu clock, I get 800 MHz. Isn't the overdrive mode 1000 MHz?
When I read the imx gpu document, it says that if I enter the command as follows, it will change to overdrive mode:

sudo echo "overdrive"> /sys/bus/platform/drivers/galcore/gpu_govern.

However, my file system does not have "gpu_govern". Is there a way to change it?
