It’s not known either way yet, but unless they offloaded it to a separate firmware like Nvidia or Intel, it’s not possible for them to do in Linux due to HDMI patents. The way the other vendors avoided this is to use a separate component that does everything internally, so none of the code is in the drivers. AMD doesn’t do that historically, and thus can only support such features with closed source drivers/OS.
We are now at the point where lobbying looks like a moral option compared to this shit
