Set Mali GPU operating frequency

Hello, I am currently using Pixel6 and Pixel8 with GPU

Mali-G78 MP20, Mali-G715 MP7 respectively.

For previous devices, setting GPU frequency manually was possible setting

"userspace" as governor and using "set_freq" to choose among available frequencies but it seems outdated.

Is there any way I can manually set Mali GPU frequency?

If this isn't a right place to ask this type of question, where should I ask it?

Thank you
