For anyone on Windows stuck doing this, I've had decent luck with the Snappy Driver Installer. (https://sdi-tool.org/)

The project is open source, can store a complete collection of all drivers offline, and can detect and update drivers. Please do note that you should always take a system restore point, as I have had a few issues with graphics drivers installed with the tool in the past.

Unfortunately, I think that's their true intent...

But "potentially infected" is mostly paranoia scaremongering, unless you deliberately go for the ad-encrusted huge-flashing-download-buttons sites(and probably even those are OK) --- there's plenty of other community-based sites (like the one linked here) which I've used before for various software, and I'd say a lot of times I trust the community even more than "official" sources. Especially when the latter has commercial interests to uphold.
