looks like you need to extend Carousel, and setNestedScrollingEnabled(false).

for example:

@ModelView(saveViewState = true, autoLayout = Size.MATCH_WIDTH_WRAP_HEIGHT)
class HorizontalCarousel(context: Context) : Carousel(context) {

    init {
        isNestedScrollingEnabled = false
    }

    override fun createLayoutManager(): RecyclerView.LayoutManager {
        return LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false)
    }

    ...

}
