Cannot alter Vcore Loadline Calibration

[The old boy]

Hello everybody
I have a GA-Z77X-UP7 REV. 1.0 Gigabyte board. I have been following tinytomlogan's excellent video but I am stuck here. I should be able to change the setting from Auto to Extreme. When I double click on Auto there are no options. In fact this is the same for all the entries in M.I.T\Advanced Voltage Settings\3D Power Settings.
Any advice

You might need to use keyboard inputs like enter, + or - to change certain values.

Good support for mice in the BIOS/UEFI is a relatively new thing.

Thank you very much. + worked.
