The 60GHz heart rate sensor you're talking about (this one maybe https://wiki.seeedstudio.com/ha_with_mr60bha2) can be used with any microcontroller. It's got nothing to do specifically with ESP32, which is just one kind of microcontroller you can use it with.
Oh thats cool. I just saw a reference to ESP32 and I know they do a 60GHz heart rate unit. Some HA guys have been using it
