THe image you posted is from:

- So you would need to decompile the file,
- edit this section to your needs:

```auto
 rockchip,temp-trips = <
        60000 1
        65000 2
        70000 3
        75000 4
        80000 5
    >;

```

- recompile it and replace the old one

First of all you make a backup of your system before we trying to edit this.

Assuming the dtb is in `/boot/dtb/rockchip/` you do following:

```auto
sudo apt install device-tree-compiler
sudo dtc -I dtb -O dts -o /tmp/orangepi5plus.dts /boot/dtb/rockchip/rk3588-orangepi-5-plus.dtb

```

Then edit the file `/tmp/orangepi5plus.dts`, e.g. with `nano`.  
Then copy it back and reboot

```auto
sudo dtc -I dts -O dtb -o /boot/dtb/rockchip/rk3588-orangepi-5-plus.dtb /tmp/orangepi5plus.dts
sudo reboot

```
