Mayukh, You can use something like https://www.fpgadrive.com/
and its reference design https://github.com/fpgadeveloper/fpga-drive-aximm-pcie to connect the high speed nvme drives to your RFSoC. I think this consumes the least amount of power and provides the highest read / write speed. Although you may have to develop nvme logic.
