The additional settings are not available any longer, any power settings relevant to the use of the iGPU or discrete GPU are on the advance settings of the power plan you are using within Windows (assuming this is a laptop)
Relive is also not available for certain APU's and mobile GPU's (again assuming it is laptop)
Could you please provide info about your hardware or take a screenshot of the system tab?
Did you find what you were looking for?
I know it is in portuguese, if you can't understand what and where it is go to the Control Panel (you can search for it in the start menu or search bar) > Hardware and Sound > Power Options and select the power plan you want > Change Advanced Power Settings
