Just got this past on to me to find answers. I have not been involved on site with this particular house.
Short of it:
Had DVCL153 installed in multiple locations with Feit LEDR56/830.
Eaton BRCAF115 AFCI's tripping all over the house within 10-15 seconds.
Replaced with ELV and all work. Diff of $45 per dimmer lost.
Tech says some hallway string didn't trip but 13 out of 20 or so dimmers replaced with ELV.
He found if he had 3 cans it was ok but add in a 4th and tripping starts.
He tried all dimmers. LV, DV600, DV1000, DVCL,
And ideas great appreciated.
