How to increase vRAM for HD3000 graphics after upgrading Mac mini 2011 to Monterey using open core legacy patcher?

Hi all, has anyone figured out a way to upgrade the vRAM for the HD3000 in the 2011 Mac mini from 512MB to 1024 MB? There used to be a series of commands back in the day that would allow that, but it seems as the newer macOS versions prevents this as some of files that need to be change are "read only" now. Mac mini still runs well with Monterey OCLP, just checking if I can push a little further the graphic...thanks.

Below is the original "macrumors" posting from back in 2014:
