What's the difference between installing with and without Clover/ACPI/patched?

Guys, can anybody comment the statement that Clover/ACPI/patched must be empty during the installation of MacOS? Then if you install Clover on SSD and move all the patches into SSD/EFI/Clover/ACPI/patched you get fully working trackpad. I have 2 confirmations from other people that using this method helps to get Lenovo S340's trackpad working. Otherwise the trackpad doesn't work. For example I installed MacOS using USB with all needed patches into Clover/ACPI/patched and my trackpad doesn't work. Lenovo S340, Catalina, vanilla guide, VoodooI2C kexts.
