m17 R5, issues with BIOS 1.12.0

Hi all,

I recently received a critical update notification from SupportAssist instructing me to update my system BIOS to version 1.12.0. However, despite multiple attempts, I couldn't find this version on the official Dell website for my laptop model; the latest available is 1.10.0? Upon further investigation using HWinfo, I discovered that my PC currently has version 1.11.1 installed. Given that I acquired the laptop second hand, I'm puzzled as to why a version not listed on Dell's official website is installed? Additionally, I'm questioning why SupportAssist is prompting me to update to a version that isn't available on the official website? I've searched extensively for updates 1.12.0 and 1.11.1 on the Dell website but couldn't locate any information. Any insights or guidance on how to proceed would be greatly appreciated.

Thank you.
