Hi Perry,
I have the following in: Advanced > AMD CBS > NBIO Common Options > SMU Common
Options
CPPC (Auto / Enabled / Disabled): Enabled
CPPC Preferred Cores: Enabled
There is no setting to change the default state.
But there seems to be more reports of TRX40 users who are having the same
problem:

A while ago I was running a custom Xanmod kernel which had the amd-pstate
patchset applied before it was sent upstream.
It was an older revision of the driver of course but it was working for me.
The only requirement back then was setting the "shared_mem=1" flag on the
kernel command line.
But this flag doesn't seem to fix it for me when running linux 6.5.
