UPDATE 10-4-2020
(Importand!!!!! From now on builds will be based on an unlocked CFG so please, if you don't have one modify config.plist settings.) Updated kexts changed config.plist settings for unlocked CFG (see above for method). Included a SSDT-PLUD for cpu Recreated CPUFriend Data Provider kext Installed 10.15.4 supplemental update with no problem

Options
In my EFI you will find an SSDT-PLUG.aml

1. CpuFriend kexts in kexts folder and SSDT-PLUG.aml in ACPI/Patched folder, with plugintype1=false in config.plist
2. CpuFriend kexts in kexts folder, NO SSDT-PLUG.aml in ACPI/Patched folder, with plugintype1=true in config.plist

(these two options give the same results. CPU base freq at 600Mhz, idle freq at 600mhz, core watts 0,30 at idle, PKG watts 1.70 at idle, cpu utilazation at 4,70 % and a bit more at idle.
3.CpuFriend kexts in kexts folder, NO SSDT-PLUG.aml in ACPI/Patched folder and plugintype1=false in config.plist
(this option has CPU base freq at 600Mhz, but idle req freq is never bellow 1,2Gmhz. Core watts 0,30 and bellow at times at idle, PKG watts 1.70 at idle, cpu utilization is less than 3 % at idle

You can choose which option you like.

I have a computer with basically the same configuration as your laptop, but I can't use your EFI file, so I'd like to ask you about what bios needs to be set up.

If you downloaded the latest then you will not boot unless you disable CFG Lock in hidden bios settings

can you tell me the model of your laptop?

I have S540-15IWL GTX Laptop (ideapad) - Type 81SW but with the same specs as the model in the guide but can't enter the hidden BOIS tried many times but in vain
"Processor (Intel(R) Core(TM) i5-8265U
Intel UHD Graphics 620
"
I updated the BOIS to bwcN14WW maybe the model name changed when i updated the BOIS? idk
Is there any other way to disable CFG or do I have to modify config.plist with the options mentioned in this reply?

We have a bit different laptops.
In my repo at github I have two EFIS. Try the older one ... its before CFG.

If you have updated the BIOS (I think there was an update in February or March) thenyou must not use my DSDT you will get multiple ACPI errors and perhaps not even boot.

With out any specifics I cannot help you...

The directions (the options) are for the CFG Unlock.... !!!!!

The stock wifi/BT card works or you have replaced it with DW1820a?

I use the mainland Chinese version of Lenovo YANGTIAN-S540-14-lwl,. I have consulted the customer service staff, and it seems that my computer does not support the advanced settings of hidden bios, which bothers me very much.
