Is there any way to lock the frequency of Adreno 630 or Adreno 640 with out DVFS?

I want to know directory to mangage the frequency of GPU without DVFS.

In addition, I want to know if snapdragon profiler can lock the GPU freuqency while measuring,  I want to know how to lock the frequency.

Thank you in advance.

Actually Snapdragon profiler itself cannot lock GPU frequency.

For debug devices, we have some command to lock GPU freq, but it requires user debug/engine build and a root permission.
So do you have root permission to your device?

Thanks
