If your bios is InsydeH20(I think so) version >2016 then you can't change DVMT prealloc. Because it has rewrite protection. But you can check your dvmt with "setup_var", if that command return 0x02(64mb) then you don't have to change dvmt anymore.
And you shouldn't install High sierra because HD 520 will cause your lap can't wake up from lid/sleep(still not fix yet). So my advice is you just install sierra 10.12.6, it works perfectly.
