Yes, it is possible to disable the reset button on MikroTik devices to prevent the device from being reset to its factory settings through physical use of this button.

This can be particularly useful in environments where you want to prevent unauthorized people from modifying the device settings. Disabling the reset button is done through system settings in RouterOS.

Here I explain how to do it:

Disable the Reset Button using WinBox or WebFig

1. Open WinBox or WebFig and connect to your MikroTik device.
2. Go to System → Routerboard in the main menu.
3. In the 'Settings' tab, you will find the 'Enable Jumpers Reset' option (in newer versions this may appear simply as 'Enable Reset' or 'Reset Button'). Uncheck this option to disable the reset button functionality.
4. Click 'OK' or 'Apply' to save your changes.

Disable the Reset Button via the Command Line (CLI)

You can also perform this task through the MikroTik RouterOS CLI:

/system routerboard settings set enable-jumper-reset=no

On some specific versions or models, the command might vary slightly, so it's always a good idea to consult the specific documentation for your RouterOS version and device model to confirm the exact command.

Considerations

• Log in: After disabling the reset button, the only way to reset the device to its factory settings will be through the RouterOS command line interface or GUI, which requires administrative access to the device.
• Security: Make sure you have another way to recover your device in case you lose access to settings. Keep backup copies of settings that allow you to restore the device if necessary.
• Models and Versions: The availability of this option and the exact steps may vary depending on the MikroTik device model and RouterOS version. It is always advisable to review the specific documentation for your hardware and software.

Disabling the reset button is a practical security measure in many scenarios, but be sure to consider the implications and have an appropriate configuration management and recovery plan.
