You can use Device Tree Overlay feature to enable/disable some hardware functions without to recompile the kernel source code.

There are some ready to use dtbo files, you can also add your own dtbos to enable or disable the peripherals.

khadas@Khadas:~$ ll /boot/dtb/overlays/kvim3

• Write your own device tree overlay file, for example `example.dts`:

  /dts-v1/;
  /plugin/;
  
  / {
      fragment@0 {
          target = <&i2c3>;
  
          __overlay__ {
              status = "okay";
          };
      };
  };

This device tree overlay is to enable `i2c3`.

• Compile it to dtbo

  khadas@Khadas:~$ dtc -I dts -O dtb -o example.dtbo example.dts
  khadas@Khadas:~$ ls example.dtbo
  example.dtbo

• Move the dtbo file to /boot/dtb/overlays/kvim3

• Edit /boot/env.txt to add in node overlays

• Reboot the board
