[Internet and sound drivers for Windows 8.1 on dell vostro 3520]

Ok so, I've gotten the display driver to work with the help from D.Draker, but now I've been wondering for a while how can I get the internet and audio drivers working on it since everything has been failing for me. Can anyone please help me out

[Does my laptop even have any drivers that could work for it?]

Ok, so. For over a week now,  I've been trying to find working Windows 8.1 drivers for my Dell Vostro 3520,  i7-1255U, Intel Iris Xe graphics laptop, but to no avail! My laptop usually just supports Windows 10/11, but I just feel better with Windows 8.1! Can anyone help me find network, audio and some graphics drivers if possible? I would be thankful if there are ones which can work!
