idk about technical documents perse, but heres a news article when AMD introduced VRR over hdmi ways back, noting how vrr on hdmi wasnt a thing yet, so AMD partnered with monitor makers to use a different scaler that would make it compatible with freesync.
VRR over display port would be in the Displayport 1.2a specification sheet. VRR over HDMI (officially) is under the HDMI 2.1b sheet.
I would love to learn more about this. Know of any technical papers or references?
