hifi berry is not recognized

Good evening, I purchased HiFi digipro, I connected it to my raspberry pi 4 but, by typing aplay -l I don't see anything, I tried to delete dtparam=audio=on but nothing, the card isn't displayed...
if instead I comment the line: dtoverlay=vc4-kms-v3d
and I add dtoverlay=hifiberry-digi-pro, the next time I restart the screen remains black
