Removing grounds is never a good idea. They are there to keep the dangerous voltage potentials off the chassis and routed safely to ground.

To use a surge protector as protection against chassis voltages and depending on another device's ground for protection is foolish.

There's only one way this should even be considered and that is IF the circuit is GFCI protected.

A surge protector will not disconnect the circuit if 80ma of current flows from hot to ground. That's enough to cause cardiac arrest in healthy people...... but the GFCI will trip and shut the circuit off when it detects 7ma flowing to ground from hot.


I'm curious if you have tried the "divide and conquer" method of troubleshooting yet to try to isolate the whine. And if so, what the results were.
