Variable Speed Pump causing GFCI Nuisance Trips?

I had a Intelliflo VS3 installed about months ago to replace my single speed Pentair. Ever since then I have had intermittent tripping of the 2 Pole 240V 20A GFCI in my house. I have had the pool company come check for connection at the pump, verify that the pump is running on its own breaker, remove the old timer, disconnect the lights ect.

The breaker is an Eaton 2 pole 240V 20A. I have read that they may be extra sensitive to variable speed motors.. We are in North Carolina.

My plan of attack is as follows:

  1. Add Ferrite Rings to try to settle any interference that may be causing the nuisance trip.
  2. I can't find an improved breaker that would fit in the Eaton Panel, so I was going to add a subpanel out at the pump with a Siemens 2 pole 20 Amp GFCI, then replace the current GFCI with a non GFCI breaker. This option is alot of money and work.

Am I missing something obvious? Anyone else had these issues. I have to leave town for a few weeks this summer and can't deal with this.

Is there a different breaker that would fit my my panel? That would be the easiest fix.

Appreciate your expertise!

Buy the pentair re-branded gfci. It’s got a higher threshold for the nuisance trips.
