    You should have to set the view background color to be clear before presenting the modal

    self.view.backgroundColor = .clear
self.modalPresentationStyle = .currentContext
self.present(nextVC, animated: true, completion: nil)

    If you are using UISheetPresentationController to present. You can look at largestUndimmedDetentIdentifier.

    If you set that variable to .large your medium detent will have no dimmed background.

    if let sheet = vc.sheetPresentationController {
    sheet.detents = [.medium(), .large()]
    sheet.prefersGrabberVisible = true
    sheet.selectedDetentIdentifier = .medium
    sheet.prefersScrollingExpandsWhenScrolledToEdge = false
    sheet.prefersEdgeAttachedInCompactHeight = true
    sheet.largestUndimmedDetentIdentifier = .large
}
