Reinette,

Perhaps.  The discovery driver is somewhat it's own thing:

drivers/platform/x86/intel/pmt/Makefile:obj-$(CONFIG_INTEL_PMT_DISCOVERY)       += pmt_discovery.o

But it is automatically pulled in if you enable INTEL_PMT_TELEMETRY:

drivers/platform/x86/intel/pmt/Kconfig-config INTEL_PMT_TELEMETRY
drivers/platform/x86/intel/pmt/Kconfig- tristate "Intel Platform Monitoring Technology (PMT) Telemetry driver"
drivers/platform/x86/intel/pmt/Kconfig- depends on INTEL_VSEC
drivers/platform/x86/intel/pmt/Kconfig: select INTEL_PMT_DISCOVERY
