If my biological father is put on my birth certificate would I be able to keep my surname?

would I still be able to keep the surname I have now although it is not my mothers or fathers surname. currently, my older brothers dad is on my birth

would I still be able to keep the surname I have now although it is not my mothers or fathers surname. currently, my older brothers dad is on my birth certificate therefore I have his name. I would like my biological father on it but will my surname have to change?
