Any way to leave a family without parental consent?

Recently, I have been trying to use a free month trial for the PC Xbox game pass, to which it tells me that a parent must allow my account to use recurring billing. However, the account that is supposedly my parent in this family is an account that me and my father no longer have access to, or even know what email was used for it. Without a method of accessing that account to leave the family or change settings, is there any way I can leave the family or change anything without parental consent? Thanks.
