I ended up forcing the driver in a crude way, just for the purpose of seeing if it could work at all. I edited the inf file to change basically all of the hardware IDs in certain areas and enabled Test Signing mode. It successfully installed, but it was basically unusable. Pretty sure that RTX Laptop GPU being compatible with Windows 7 was a big lie from Nvidia, or a sloppy misfiling.
I do still wonder about if anyone has gotten any RTX 30 series laptop GPU running at all on Windows 7. This experience has also made me question whether or not a 3090 TI will actually run on Windows 7, though I think I have seen someone on reddit claiming that they have that working on Windows 7.
Oh well, I didn't have any touchpad drivers to make the touchpad on that laptop work on Windows 7 anyway.
