[Problem] GPU not recognized anywhere Dell M4800 + RTX 4060

Hi, guys, I have bought an RTD 4060 MXM-A and it just doesn’t work on my Dell Precision M4800. It was also tested in Alienware M17xR4 by another user and it worked, although it was hot, but still.

My laptop acts like it doesn’t see it. It is not visible in Windows (Device Manager) and Linux. BIOS definitely knows it is there, Switchable Graphics option isn’t greyed out, and when it is turned off, after BIOS settings are applied laptop reboots, but then shuts down and starts again, also reversing the change.

Resizable Bar is not an issue, this GPU works without it, I have also modified my BIOS so it has it now.

Any clue on what to do? I need this GPU to work ASAP. Any help would be appreciated.

@dsanke sorry for tagging you, I hope you don’t find it annoying or offensive. I saw your numerous BIOS mods for Clevo laptops, including mods to support RTX GPUs. Would it be possible to do the same with my M4800? And if it is - please, explain how to do it.
