Hello,
Only a few colleges ask for it , rest colleges only ask for other required documents. Its better to get one to avoid any issues in the future counselling procedures.

as you know that cutoff changes every year depending on various factors like difficulty level of the exam questions , number of candidates appearing and the recent COVID19 crisis etc.

You can use careers360 college predictor to know the colleges you can get at your NEET score;- https://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer

Hope this helps
