Need help understanding BIOS update order sequence and version

OptiPlex 7050 Small Form Factor

I recently got this desktop and I am in the process of updating the BIOS.

• Installed version is 1.5.2
• Last version is 1.27.0

In the "Important information" paragraph of the 1.27.0 version, I read "If your BIOS version is earlier than 1.7.6, you must update the BIOS to version 1.7.6 before upgrading to the latest version."

The problem is that if I insert my service tag, I can only see 4 BIOS versions 1.27.0 down to 1.24.0 but no 1.7.6

So I searched on Google and I found this DELL page that seems to contain 1.7.6.

The problem is that I am not sure that this is the correct version and I am scared to brick the computer.

Any help please ? Is the page I found for 1.7.6 the correct one ?
