Rooted Pixel 6 CPU DVFS control without userspace governor

So I recently rooted my Pixel 6 (Android 13) using Magisk and tried to control the CPU frequency, but it did not have userspace CPU governor. I tried to set scaling_setspeed in /sys/devices/system/cpu/cpu0/cpufreq/ with no luck. Also tried setting scaling_max_freq and scaling_min_freq using the maximum frequency and scaling_governor as performance mode, but when workloads start, the frequency would drop. Is there a way to set and fix the frequency without installing userspace CPU governor? It was to my understanding that performance mode would keep the CPU at max frequency, but even then, that was not the case.
