In this post:

the solution was to change from serial_a to serial_f in the tegra_sinterface.dtsi file but I’m not sure where to access it.

You need to check the HW connection and modify it in the device tree like below.

                                       imx274_a@1a {
                                                compatible = "nvidia,imx274";

                                                physical_w = "3.674";
