A data-binding solution inspired by @Vishal's answer

    @BindingAdapter("app:enableCollapsingScroll")
    fun setCollapsingToolbarLayoutScrollEnabled(collapsingToolbarLayout: CollapsingToolbarLayout, enabled: Boolean?) {
        val lp = collapsingToolbarLayout.layoutParams as AppBarLayout.LayoutParams
        if (enabled.orFalse()) {
            lp.scrollFlags = AppBarLayout.LayoutParams.SCROLL_FLAG_SCROLL or AppBarLayout.LayoutParams.SCROLL_FLAG_EXIT_UNTIL_COLLAPSED
        } else {
            lp.scrollFlags = AppBarLayout.LayoutParams.SCROLL_FLAG_SNAP
        }
        collapsingToolbarLayout.layoutParams = lp
    }
