Force 2011 MacBook Pro 8,2 with failed AMD GPU to ALWAYS use Intel integrated GPU (EFI variable fix)

There were two possible solutions to fix a MacBook Pro 8,2 with failed AMD GPU :
1) Pay a sh!tload of money to Apple to replace a logic board, or buy it from eBay ---> very expensive and will also fail after some time
2) Either do BGA reballing ($50) or BGA reballing with AMD chip replacement ($35) to guarantee a success, less than $100 in any case

Any of these two solutions requires money... But now there is a third solution,
a purely software fix which you can do for FREE :
it is possible to completely disable a discrete GPU by a EFI variable, forcing it to use integrated only all the time (even while booting!) to
make MBP usable again!
Here are the instructions - https://forums.macrumors.com/threads/force-2011-macbook-pro-8-2-with-failed...

After this wonderful purely software fix, the failing discrete GPU is completely disabled
and you can't even enable it in gfxCardStatus ;-)
