Lenovo L340 Laptop Won't Boot, ACPI Error and IntelFrameBuffer Issues (Opencore)?

Hardware:

CPU: i5-9300H

GPU: Intel UHD 630 (w/ Nvidia GeForce GTX 1650)

RAM: 8GB

Motherboard/Laptop model: Lenovo L340-15IRH

Screen(s) Resolution: 1920x1080

Audio Codec: Realtek ALC257

Ethernet Card: Realtek PCIe GbE (8168)

Wifi/BT Card: Intel AC 9560 (A370)

What guide/tool I followed:

Dortania guide official, following the Coffee Lake Plus config.

What part I got an issue with:

Won't boot from USB to installer. Tried all sorts of variations. Intitially I was getting an IntelFrameBuffer panic, but added npci=0x2000 and -igfxdvmt to the boot-args and that seemed to help. Now I get to an ACPI error which craps out after PCIConfigurationEnd, reporting the following: ACPI Error: [\_SB_.PCI0.PAUD.ONTM].

The GPU is patched in the config.plist as provided below.

What files/config I am using:

OpenCore. My config.plist is as follows: https://pastebin.com/kHFtuK90

Extra Info:

Dedicated GPU is diabled with -wegnoegpu. BIOS options don't allow for much tweaking, can't set DVMT for example. Using boot args: -v -wegnoegpu npci=0x2000 -igfxdvmt keepsyms=1 debug=0x100 alcid=11
