[Request] Add support for Dell Latitude 7480

[Ibrahim-Al-Najjar]

Hello 👋,
First of all, thank you for maintaining nixos-hardware and supporting the community 🙏.

I noticed that the Dell Latitude 7480 is currently not available in the repository. I’d like to request adding support for this device.

Device Information:
Model: Dell Latitude 7480

NixOS version: 25.05

Kernel version: 6.12.41

Current Behavior:
There is no dedicated hardware profile for this model in the repo.

I’ve been testing NixOS on the device and can share details (modules, quirks, working/non-working hardware).

Expected Behavior:
A dedicated profile (similar to other Dell Latitude models) to make configuration easier and more reliable for Dell Latitude 7480 users.

Additional Context:
I am willing to help by testing, providing hardware information (lspci, lsusb, dmesg, etc.), and documenting quirks.

Thank you for your time and effort 💙
