DTAA Support for NRIs?

Does Zerodha support not deducting TDS inline with the DTAAs that India has signed?

Most other institutions like HDFC and Kotak comply with these allowing for lower/no TDS rates. Zerodha being a broker is the only responsible for deducting TDS on Capital Gains but these gains are exempt under a lot of DTAAs.

I just availed this exemption from HDFC and they only needed my Tax residency certificate and Form 10F as required by the IT Department.
