What is the ruling on money deposited in an interest-bearing account and designated for the questioner by his father, and how can he dispose of it if it is not Islamically permissible for him?

This money is the father's property, given as a gift to his son. It is most probable that the son should take the money and benefit from it, because some scholars hold the view that inheriting or being gifted unlawful money permits the heir and the recipient of the gift to benefit from it. Also, because the usurer here is a disbeliever, unlike a Muslim who engages in usury knowingly.
