Until now, this has been hardcoded as a downstream patch in lld. Add it to the
driver so that the private patch can be removed.
PS5 only. On PS4, the equivalent hardcoded configuration will remain in the

Until now, this has been hardcoded as a downstream patch in lld. Add it
to the driver so that the private patch can be removed.
