Almost the same HW here.
3970x CPU, Gigabyte Designare TRX40 rev 1.1, BIOS v. FD.
linux kernel v. 6.4.7
No combination of settings activates amd_pstate driver. Error in syslog:
kernel: amd_pstate: the _CPC object is not present in SBIOS or ACPI disabled
In bios there are available setting CPPC and prefered cores, all enabled.
