[KB7425] Adjusting the graphical pre-boot FDE login screen in ESET Endpoint Encryption and ESET Full Disk Encryption

The EEE FDE UEFI Options Tool requires Administrator rights (elevated access) to run.

- Force Text Mode: Changes the pre-boot FDE login screen to the previous text-based login screen.
- Allow Screenshot: Enables the user to take screenshots of the pre-boot FDE login screen by pressing F9 on their keyboard. The screenshot is saved as a PNG and can be found in the EFI\deslock\ directory.
- Force On Screen Keyboard: Can be toggled to force the on-screen keyboard to be displayed in the pre-boot FDE login screen even if no touch screen is detected.
- Use Poll Events: Poll for events, instead of using the UEFI event mechanism.
- Show Logo: Toggles the ESET logo displayed after entering FDE credentials to boot Windows, which is different from the banner displayed above the main control. Users can also customize the logo.

- Idle Shutdown: Shut down the system after a certain amount of idle time. 0 = off, max = 7200 (2 hours). Idle means no keypress or touch input. Idle timer is not active on TPM unlock countdown screen, or Safestart screen.
- Rotate: Can be adjusted to force the pre-boot FDE login screen to be displayed in a certain way, such as portrait or landscape. F8 can be pressed while in the pre-boot FDE login screen to rotate the screen.
- Zoom: Can be used to adjust the zoom at the FDE pre-boot login screen.
- Max Screen: Can be adjusted to force the pre-boot FDE login screen to be drawn in a specified resolution.
- debug_flags: If the user experiences a problem then support may request a specific value be entered here, to help diagnose issues with the pre-boot FDE login screen.
