It's now possible on iOS and tvOS 14.
You have to use the contentInsetsReference property.
You can set for a specific NSCollectionLayoutSection:
swift
let section = NSCollectionLayoutSection(group: group)
section.contentInsetsReference = .none
Or you can set for the whole UICollectionViewCompositionalLayout using UICollectionViewCompositionalLayoutConfiguration:
swift
let configuration = UICollectionViewCompositionalLayoutConfiguration()
configuration.contentInsetsReference = .none
