How to Disable or Turn Off the LCD Screen on Sophos XGS 2100 Firewall

Question

Hello Community, 
 
 I am encountering an issue with the Sophos XGS 2100 firewall and need assistance with disabling or turning off the LCD screen. I have not been able to find a direct option in the management interface to power off or disable the screen. 
 
 Is there a setting available through the management interface, or do I need to use specific CLI commands to achieve this? I would appreciate any guidance on the correct steps or configuration. 
 
 Thank you for your time and assistance.

Hello Yousef, 
 you could pull the cable inside from the logic board behind the display. Of course you would need to open the device for that. 
 The buttons would be disabled like that as well.
