I think something else may be wrong?

I switched my kernel config to 100 HZ and the problem persists.

So the question remains, is it possible to utilize turbo boost (in Linux)
without the high pitch noise from the ACPI processor module?

Again, when the module is not loaded, no matter what HZ, there is no high
pitch noise.
