Tested your OC files on my E7270 without touchscreen. 

I disabled all the I2C stuff pertaining to the touchscreen

Issues:

Sleep shuts down computer and encounter KP error message when started up again which means sleep isn't working. Is it working for you?

Graphics has a hazy color //fixed it by removing AAPL,GfxYTile and AAPL00,override-no-connect patches from Device Properties

 

I was able to enable Brightness control with Fn+F11 and Fn+F12

Also added kext to enable Realtek SD Card reader

 

I have been able to put together some files and have sleep working on my E7270 and E7470 if it doesn't work for you either.

in mine sleep not reallly working good, if too long sleep it goes black screen. not yet touching more for the sleep function coz usually I'm shuting down my Laptop if not use it.

my graphic is working properly, I'm forget to get set normal after patch using hackintool (2048 MB) but is OK on mine.

on Cinebench get 714 for CPU and 331 for single core. Is good result or not?

My system using 1 TB NVMe Patriot P300, 16 GB PC2133 and 4 OS (Catalina, Mojave, WIn 10 and Ubuntu DDE).

 

How to enable Fn+F11 and Fn+F12 ? until today can't get work for it.

And what kext for enabling Realtek SD Card reader?

For Brightness:

Add SSDT-BRT6.aml and replace your SSDT-OC-XOSI.aml with mine and add patch to ACPI

Comment: BRT6,2 to BRTX,2, with SSDT-BRT6.aml

Find = 14204252 543602

Replace = 14204252 545802

 

For SDCard reader, add Sinetek-rtsx.kext to Kernel

 Any clue for disable brigthness on Fn+S/Fn+F6 (decrease) and Fn+B(increase) ?

 

- Card reader is show on PCIe Hackintool, should I add to device properties?

We recently posted an article about Realktek PCIe card readers (click on Home to get there) and there is also a dedicated thread about them in the Card Readers section. Please refer to that. Of course, without an SD card, you won't be able to do/test much thereafter...
