Doubt in DGCA computer number creation

Hey fellow avgeeks! I am going to apply for my computer number. From what I understood after seeing a lots of videos from YT is that DGCA is very strict in terms of the verification process. I am basically from Tamil Nadu but did most of my schooling from Gujarat. The thing is due to surname confusion in the north/west and south, my aadhar card & passport has my name as let’s say - “abc def” where “def” is my father’s name but in Tamil Nadu we don’t have surname and simply take the initial from our father’s name(Just trying to give context relevant to the topic, not boasting or mocking anyone :)) ). My 10th and 12th Mark sheet has name let’s say - “d abc”. My question is will DGCA reject my application and if so then what are the ways to prevent it? Should I attach some sort of affidavit which states the reason for mismatch. You can share your experience if you went through the same. Please help me with this and if possible the proper method to handle. Thank you❤️
