You post in the Latitude E5xxx Series; pease specify your laptop model. Haswell-based E5x40 I presume. Please post a zipped copy of your bootloader's config and, if possible, an IOReg extract + SysProfiler extract. Very little we can do without minium information and, in all likelihood, you have some incorrect settings.

No need for the following iGPU properties on Haswell graphics:

 

framebuffer-fbmem             00009000        DATA
framebuffer-stolenmem         00003001        DATA

Make sure to remove them, reboot and reset NVRAM at OC Picker before booting Big Sur.

 

Re: wifi, no idea about the hardware you got in place so, you'll have to post full specifications of your (E5x40 ?) laptop, whatever that may happen to be.

 

Now need to look into your patched DSDT and SSDT in case those add conflicting stuff for your graphics.

Checking up your OC config, I see that you do not inject the patched DSDT; wise decision given that it probably contains erroneous stuff. I already noticed this patcher the iGPU:

            Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
            {
                If (LEqual (Arg2, Zero))
                {
                    Return (Buffer (One)
                    {
                         0x03                                           
                    })
                }
                Return (Package (0x06)
                {
                    "AAPL,ig-platform-id", 
                    Buffer (0x04)
                    {
                         0x06, 0x00, 0x26, 0x0A                         
                    }, 
                    "hda-gfx", 
                    Buffer (0x0A)
                    {
                        "onboard-1"
                    }, 
                    "AAPL00,DualLink", 
                    Buffer (0x04)
                    {
                         0x01, 0x00, 0x00, 0x00                         
                    }
                })
            }

which is incorrect (missing fake id 0x0412 and DualLink property invalid on Haswell iGPU).

I'm sry I'm a beginner but idk how to edit the efi after I already installed it.

You gotta do your homework. I see that you have Clover Configurator app so look out for its cousin OpenCore Configurator. Failing that, if you read the Dortania documentation, something you really should do, you'll find references to tools such as ProperTree or other plist editor (eg: Xcode, Plist Edit Pro, etc.).

 

I also invite you to learn how to take screenshots in macOS, something detailed in the keyboard Preference Panel. Screenshots are a million times better than poor/unreadable shots from smartphones.
