Can unbelievers change their attitude towards God in Hell?

A popular (Eastern Orthodox) view of afterlife proclaims that God's presence is akin to torture for an unbeliever (Hell) and akin to bliss for a believer (Heaven). It claims that Heaven and Hell are different responses to presence of God, rather than 2 different places. This brings me to my question. From the Eastern Orthodox perspective can unbelievers change their attitude towards God in the afterlife, and thus turn their Hell into Heaven?
