In the PicoADK Firmware (PicoSDK based) we are overclocking the RP2040 to 402MHz successfully.
It would be great to see this in the Arduino-Pico package. So far only 1-2 chips out of >100 did not work properly.
This might require to set flash clock divider to 4. Not sure how this can be achieved with the Arduino-Pico core.
This is the way I am doing it using the PicoSDK.

The overvoltage should be adjusted according to this chart:
