Yes, we can't choose our likes and dislikes. But we still have the God given freedom to override these to do something just because we consciously choose to do it.
But you're just ignoring
why you might choose to override your likes and dislikes. There is no "just because" we choose, you either make that choice for some reasons or for no reason. You keep trying to separate the notion of 'you' from any reasoning about how you make choices.
If you decide to override a like or dislike it will be because there is something else that is more important to you at the time - and that, in turn, will be because of the way you prioritise things and, perhaps, how you were feeling at the time, which will, in turn, be because of recent experiences and experience and beliefs that you have built up over your lifetime, and so on. There is no 'escape' from the chains of (internal) cause and effect because such an 'escape' would be an escape from being yourself, which makes no sense at all.
It really does have nothing to do with whether you are physical or not. The very idea of being a functioning mind who makes choices
necessitates the cause and effect. Without it there is no 'you' that can make a choice.
