[Request] Lenovo Legion Y540-15IRH - Enable Above 4G for NvStrapsReBar

Hello all,

I’m trying to get the Above 4G option enabled in the bios, tried with setup_var but It’s not allowing the value to change. With the H2OUVE tool the option is red and can’t change it, which means it’s a protected feature? or it’s unsupported on this device?

I’m known with the unlocker tool to enable the advanced menu in the BIOS but it’s not supported with later bios versions, In my head a later version should be better, stable or more secure with the latest microcode so I’m using the latest (45).

My question: Does someone knows how to enable 4G (through setup_var) or how to enable the advanced menu to enable it over there? I’d made a dump with a ch341a programmer.
