MSR for Intel 8th-Gen Y processor VRM SVID temperature

Hi
After looking through the latest Intel architecture manual as well as the processor datasheet for the 7/8th gen U/Y processors, I haven't been able to find the MSRs for accessing the temperature of the VRM powering the processor. It looks like temperature monitoring is a part of the information that is provided to the processor through the Serial VID (SVID) interface with the VRM but I'm not sure if there are MSRs for accessing this or if they are accessible from the OS in any other way. I do know this information is present on the system as I am able to read it using a off the shelf program, but I want to be able to do this independently.

I did find the registers for reading the temperature and package power, however. They're in the architectural manual in Volume 4. The system has an Intel Core m3-8100Y processor in it.

Thank you for any advice!
