I have an already working setup with clover, with this specs:

• Laptop: Dell Vostro 14 5481
• CPU: Intel i5-8265U
• iGPU: Intel UHD 620
• dGPU (Disabled using ssdt, unfortunately. All external display outputs are supposed to go through it - if there's a way to make that work, I'd like to hear about it): Nvidia MX130
• RAM: 8GB DDR4
• Audio: ALC256 (layout-id 54)
• MacOS Catalina 10.15.2 Dual-boot with Windows 10, both on Toshiba NVMe SSD.

I tried to create an OpenCore USB to test before I remove clover, following the vanilla guide for laptops. Here's what I get when I try to boot:

Here's my EFI folder (without serial of course): OpenCore.zip
