Yes, Witcher 3 supports RTX.

If it doesn’t but there’s some mod that lets you do that that’d be cool too
Ray tracing or DLSS? Clarifying the "RTX" compatibility. Doubtful about DLSS details; some old whispers exist.
It was released in 2015. A remaster is planned for this year, but details about DLSS or RTX are still unclear.
No, it doesn't, as it came out before anything that would fall under the Nvidia "RTX" branding existed, and adding any of that is probably well beyond what's possible for a user mod. At present there's no firm information on the remastered version.
The upcoming update might include DLSS or RTX capabilities, but the original title and all current releases lack these features. Since it launched over five years prior to RTX's introduction, there aren't genuine RTX modifications. RTX additions must come from the developers directly, and no mod claiming to be RTX is actually valid at this stage.
