hello !
we are currently passing EMC tests too, and we get those 80Mhz harmonics too...
did you test the software solution only ? (reducing GPIO configured in output current) @marko.brelak ?

ESP32-U4WDH crystal mandatory ?
Hello,
I was using a ESP32-PICO-D4 and had no trouble (except hand soldering because of LGA package format ... which is a pain).
I moved to ESP32-U4WDH and I can't start the ESP32 (nothing on serial on boot, and impossible to flash).
Soldering is good.
I routed and VCC, GND, IO0, CHIP_PU.
