I'm having a similar issue, we ordered Lattitude 5540's not sure what this safeBios but it's making PXE booting Via KACE impossible due to drivers needed in the KACE PBE. Even using the integrated thunderbolt adapter is not successfully booting.
2024.02.13 - Just updated bios via regular MS update, now when the DELL emblem displays during boot I get to see "Secured by Dell SafeBios". I dislike clutter and would greatly prefer this message not display. When will DELL learn that people don't like annoyances. Remove it on the next update. I seriously will rollback the safety to get rid of this message.
Found solution with Dell Support. BIOS / Storage / RAID was configured. Changed that to ACHI. Rebooted and now Win11 will let me see the local hard drive to load Win and wipe the system.
I found the solution to this, you'll have to go to advanced startup in Windows, save your work before restarting, then when you reboot go into Troubleshoot, Advanced Options, then UEFI Firmware Settings. By default the POST time is set to 0 seconds so you can't press F2 to load into BIOS on startup.
@Periodic94 FYI on my Latitude 3440 (BIOS 1.13.0) with Win11, the option was "Restart now" under Settings -> System -> Recovery -> Recovery options -> Advanced startup. I was then able to press F2 or F12 during reboot.
