Using the example above, if a CPU core is overheating, can you down clock that core using and instruction run on another core? I don't actually know that much about how the hardware actually works at that level, so I am genuinely asking.
IIRC clock control doesn't need to be done in SMM, especially PROCHOT which is a hardwired thermal shutdown. That said, power management is one of the things SMM was originally designed for, so it may be used for some of that.

If it is critical it should not be running on same cores

There's a hardwired emergency shutoff but you probably want the BIOS to set the fans to maximum long before the computer just shuts off.
