Warm Greetings & welcome to Lenovo Community, happy to have you here.
As I understand that you have query regarding OS installation in T440.
The OS Optimized defaults is basically required when you are installing Windows 8 and above.
And if it is enabled, some other settings are changed automatically, such as CSM Support, UEFI/Legacy Boot, Secure Boot, and Secure RollBack Prevention.
I hope the above information helped you.
Please provide the requested detail to proceed further.
