Dear Rahul
There is no restrictions in claiming Refund for Un-utilised input on Export of goods with Lut , in case you have claimed the Duty Drawback .
Yes As per Rule 96(10) , the Supplier cannot claim refund for the IGST paid on export , who has been availed benefits under Notification 78/2017 Custom & Notification 79/2017 Custom. but the also been withdrawn by Notification 16/2020 CT .

So in term of Rule 89 , you can claim ITC refund for Unutilised ITC for export without payment tax

Yes... I agreed to Mr Pankaj Rawat Ji view...
