OCLP EFI Boot not showing on boot

Hi Everyone, I am having a problem with the EFI boot not showing up on boot after pressing the ALT button.
I have a GL702VSK Asus Laptop with Intel Core i7-7700HQ and NVIDIA GeForce GTX 1070.
I was able to successfully install High Sierra MacOS on it, and I like to upgrade it to Ventura or Sequoia using OCLP. I downloaded Sequoia MacOS and created an installer with it on my thumb drive using the OCLP tool, and then used it to build and install opencore on the EFI partition of that Thumbdrive, restarted, and hit ALT, but nothing is showing up, only the boot screen to select MacOS, not the EFI boot for OCLP.

Here's what I tried already:

1. Switched thumbdrive first in BIOS.
2. Tried restarting or even shutting down the laptop while keeping pressing the ALT button.
3. Tried both Sequoia and Ventura Mac OS.
4. Tried a different thumb drive and 2 other external SSD drives.
5. Tried 3 different ports.
6. Tried an external keyboard.
7. Installed Tahoe on VMware and made a Thumbdrive MacOS Installer from it.
8. Tried following the steps in this article: https://dortania.github.io/OpenCore-Legacy-Patcher/BOOT.html
9. Tried making a separate partition and then installing macOS in there.

Keeps getting normal boot selection and not the EFI Boot from OCLP.
Any help will be greatly appreciated.
