I'm confused like where is OC 0.8.5, i would assume that was a typo
Did you get any problems with Sleep or Brightness? Like you, i also wanted to test out the efi on Monterey before actually going to Ventura, i used -igfxsklaskbl but it would break backlit keyboard (fixed with -igfxblr), not being able to wake up from sleep + just a black screen, and no being able to turn the brightness on and off on the Built-in display
My laptop is E7270 like Herve's but just OC instead of Clover
