Intel XTU - Greyed out Values

[CH18]

Hello, 

I downloaded the latest version of Intel XTU to underclock my voltage as my laptop runs hot when gaming. From my understanding, I need to lower the core voltage. However, that option is greyed out and is not allowing me to alter the values. I have an Intel Core i7-8750H, and Windows 11 23H2. I also reverted my BIOS to default settings, but that has not worked. Please let me know how I can make it so I can alter the Core Voltage and all other values. 

Thank you.

Your H processor is not supported by XTU.  XTU only supports X and K processors.
