Change Video card IMAC 27" late 2010 Nvidia Quadro 2000M for metal support

[alecoss]

I have an imac late 2010 27" with i7 with AMD hd 5750 1gb video card that does not have metal support, I also have an MXM Nvdia Quadro 2000M video card with 2Gb of ram and I would like to replace it with the AMD one to have Metal support and install Big Sure. Reading various posts I noticed that many have replaced the cards with the quadro Kxxxx series: can someone help me in modifying the system to be able to use this video card?

Thanks everyone for the answers.
