Is SBTR stamp obtainable via Indian court without PAN, documents?

I am Amy from STI, Korea. Our company has a contract with an Indian company located in Mumbai, and to give the contract legal binding force, we want to put an SBTR stamp on the document. However, from my research, e-SBTR is only available for Indian residents since we don’t have a payer ID or PAN. I have heard it might be possible to obtain an SBTR stamp through an Indian court, and I would like to know if this is true and what conditions or documents are required. I’ve already contacted the Indian embassy in Korea, but they only mentioned the ‘Apostille’ process.
