He already does! But this ringing can be different in both probes, so that subtracting of both channels might result in a partial non-vanishing.

Well, this ringing might not be too bad, where he measures it. But at Rsense, there should no be any relevant ringing! So, we need to know, whether the ringing comes from the probe or anything else. Reverse recovery time might be too high, or unsane inductances of wiring could be present.

In any case, there should be a proper routing of lines and proper decoupling of MOSFET module. If ringing still exists, then it can be tried to low pass filter Vsense a bit...
