Hi Everyone,
I have been trying to install macOS Ventura on my Dell Latitude 7480 (non-touch) Laptop for some days now and I haven't been able to do so. I have tried almost everything.
I have done all the required changes listed in this code in the bios.
Whenever I try to boot into macOS recovery it runs code for some time and then the laptop restarts. I have also tried flashing Ventura dmg file onto the USB using "etcher balena" and then copying efi file in it but it also didn't work. The apple logo shows up, the line loads up to 30% and then the laptop restarts.
I read online that you have to use USB 2.0 port to install it. Since there is no USB 2.0 port on my laptop, I was installing it using USB 3.0 port so maybe that is the issue. I read that you have to map the USB port and place some "USBMap.kext" file in the kext folder. Since there was file with such name attached to this code. I thought that it may work but it didn't.
My Laptop Specs:
Dell Latitude 7480 (non-touch) with fingerprint scanner
Core i7-7600u (Kaby Lake)
8gb ram
Intel HD Graphics 620
FHD Screen (1920 x 1080)

Awaiting your assistance.
Your help will be highly appreciated.
Thanks in advance.

For disabled you can use this tool: OCAuxiliaryTools, I will write a guide later.
For remap your own USBmap, you can use this tool: USBToolBox, It is easily used follow the instructions here: https://chriswayg.gitbook.io/opencore-visual-beginners-guide/alternatives/usb-mapping-on-windows.
Both tools support Windows.
