Can father be forced to continue voluntary financial support?

A is not under any legal obligation to perform ‘X’ for B, but still does so out of goodwill or moral duty. Later, A and B develop a dispute, and A threatens to stop doing ‘X’ for B. Stopping ‘X’ suddenly would severely impact B, depriving him of basic amenities and affecting his right to life and dignity. Can A be charged with criminal intimidation, and can he be compelled to maintain status quo and continue providing ‘X’? Here, A is the father, B is the elder son, and ‘X’ refers to financial support. This is also in the context of alleged coercive conduct including eviction threats, provocation, physical violence, and attempts to silence the son.
