TMP 453-M: Why is VRAM option on BIOS greyed-out?

This machine has 4GB ram and ~2GB integrated graphic memory, but most of my games only see 64MB VRAM so they don't run. I tried to change this in the BIOS but the option seems greyed-out. How can I change this?

 

Note: I don't have any Supervisor password set, nor a user one.
