Need advice to change my date of birth in 10th certificate.

Hi, my parents wrongly put my date of birth as born in 2005 in school records, and all other documents such as Aadhar, 10th Certificate, PAN Card etc. However, while renewing my passport, i realised my actual date of birth was in 2004. I even have the original birth certificate issued by competent authority (registered within 14days of my birth) and a temporary hospital birth certificate (with doctor signature) proving my birth. I had planned on first entering my name in my birth certificate (as deadline is Dec 2024), getting my Aadhar card data changed, and using it and the birth certificate as proof for all further changes. However the question about changing my DOB in 10th certificate stays. I need advice regarding this entire fiasco, basically my parents made me live under a false identity and I am trying to clean my slate now. They even had a handwritten birth certificate (which has no entry in Birth Registrar as verified via RTI) and used it for my school records. Please advise me at the earliest on how to approach this problem. Please let me know if there are any repercussions as well for my parents. I need to fix this issue within next 3 years so I can also appeal for change of DOB in my College Records. I would be grateful to contact any lawyer for proper discussion regarding this matter.
