You can simply handle it like this and modify the code according to your needs

val scrollState = rememberScrollState()
var verticalScrollEnabled by remember { mutableStateOf(false)}
BasicTextField(
    modifier = Modifier
        .onFocusChanged {
             if (it.isFocused) {
                 verticalScrollEnabled = true
             }
         }
        .verticalScroll(scrollState, verticalScrollEnabled),
             value = "LONG TEXT",
             onValueChange = {}
)
