[request] help unlock advanced settings for dell 5676 desktop BIOS (Insydeh20)

I am trying to unlock the hidden settings in this BIOS. I have H2oEZ and H2oUVE software, I can see the options I want under the string list in H2oUVE, but I don’t understand how to add them to my bios or replace existing menus. Can anyone tell me what I am missing please?
