Jurors are due to visit the former New England Patriots player's home Friday.
The judge previously ruled jurors would get to see his trophy case and personal items in Hernandez's home when the 2013 killing took place.
On Thursday, prosecutor Patrick Bomberg told the judge additional trophies and religious items have been added since the killing.
He compared it to Simpson's home being manipulated during his murder trial to add photos and a Bible to portray Simpson as a religious family man.
The judge said new items couldn't be displayed, and she asked for a list of the items prosecutors objected to.
