Hello

If your Aadhar has a Delhi address but you have a UP domicile, you should use your UP address for the NEET form and during UP Counselling. For state quota and EWS, what really matters is your domicile certificate, not what is written on your Aadhar. Aadhar is mostly for ID Proof.

For the EWS certificate, your parents' address and income in UP are important. You do not necessarily need to update Aadhaar if your domicile and EWS certificates are from UP.
