How to Fix the “Secure Boot Can Be Enabled” Issue?

I encountered the “Secure Boot can be enabled when system is in user mode” issue while trying to enable Secure Boot from BIOS/UEFI settings. After making the required changes, the system started working normally, but I’m concerned about whether incorrect Secure Boot or BIOS changes could impact existing data or make files inaccessible. Has anyone experienced data loss after fixing this issue, and would using trusted data recovery software be a safe option to recover important files if something goes wrong?
