I think there is no UPI payment method brother. Are you from India?. If so It's not a big deal getting an International debit card from bank. And you can make payment through Paypal by using that debit card. But I'm not sure that all the International cards of all banks will work with Paypal because in my case three years back when I tried to purchase 'construct 3' I have account in Federal Bank and SBI. First I tried Federal bank card but that's not worked with paypal. I have contacted so many times but no solution from the bank side after that I tried SBI platinum debit card. it works well with paypal no issues. Now I'm using SBI global visa card.
If you are not interested to go to the bank branch I think there is an alternate option you can open a digital bank account and also you can apply for a 'Virtual debit card'. Hope it will work
