Can you hypnotize a bi person in to being straight?

my best friend just realized she is bi and she is not happy with that. She wants to stop the like feelings for girls and only like guys. she just wants to get the bi thoughts out of her head and live a straight life. Is there a way hypnosis can turn someone bi into straight. She knows you can't be hypnotized to do something she doesn't want to do, but she wants to get the bi thoughts out of her head and only like guys.. can she get hypnotized to be straight if she really wants to be changed and stop liking girls. do you think there is a possibility that it can change her if she wants to be changed into being straight?
