No idea why you are deleting the PNLF from Field(PNVA...

I restore my old DSDT and I try to remove my old brightness patch. High Sierra starts and the brightness works, I hope it's correct.

There are still remnants of previous incorrect patches.
Patch based on ACPI/origin.

I remove my old DSDT from ACPI/patched and I use DSDT from ACPI/origin without patch. I only correct the errors and High Sierra didn't boot.

The patches you made to ACPI/patched/DSDT.aml are incorrect. Do not make changes to existing code without purpose.

The error at post #16 shows only if DSDT don't have:

Code: 
Scope (_SB)
    {
        Device (PNLF)
        {
            Method (_INI, 0, NotSerialized)  // _INI: Initialize
            {
                If (CondRefOf (\_SB.PCI0.RP01.PXSX._OFF))
                {
                    ^^PCI0.RP01.PXSX._OFF ()
                }
            }
        }
    }

Can I add this in my DSDT in ACPI/patched or it's wrong?

Edit: I noticed that in my DSDT there isn't _SB.PCI0.IGPU but only _SB.PCI0.GFX0. I have on the config.plist the hotpatch "change GFX0 to IGPU".

You should not be adding any PNLF to DSDT.
See brightness guide (it uses only SSDT-PNLF.aml):
