Yep. "Any goal scored or created with the use of the hand or arm will be disallowed [from] this season even if it is accidental." https://www.premierleague.com/news/1263332
It seems that way. There have been a couple of incidents this season where VAR has disallowed a goal even when the handball was clearly accidental but if it is a defender doing the same thing then it's not necessarily a penalty.
