Does OCLP has a tool to disable discrete GT650M?

Hi there! I’ve picked up 2012 MacBook Pro 15 Retina A1398 with GeForce GT 650M on board. And discrete video definitely has some problems. Screen randomly turns off in 10-15-20 minutes. It was complicated, but in 3-4 takes I’ve installed Sequoia. On Sequoia it else just freezes.

Anyway, chat gpt, this tiny liar, was saying that OCLP has some tool to disable discrete video. I had to give this Mac for hardware diagnostic in 10 minutes after Sequoia installing, so I didn’t have enough time to look at all possible settings in OCLP. So, can OCLP help me?

P.S. coolers were working almost like the biggest airplane An-225, which was destroyed by russians. Probably Sequoia can be too much for this Mac. It’s top version of 2012 MBP with 16Gb of RAM, but it’s still 2012… What macOS can be better for this old guy? It seams I’ve patched Sequoia (WiFi works), but I’m not sure..
