uBEC, SBEC interference

Hi, has anybody experienced interference from switched-mode voltage regulators causing problems with the IMU’s etc in a CUBE
My best placing is under the FR4 plate the CUBE is mounted on, there seems to be two construction types for these devices, some have a flat heat sink and some have a metal can over the components to minimise emissions.
The two devices I’m considering are on the images below.
Is there a method of assessing if the IMU/gyro etc. is seeing excess RFI before commencing flight?

Thanks for reading

I have seen vibration from bad power supplies… if it’s mounted close and “hums”
