Can a HDMI FreeSync monitor understand HDMI VRR?

[Lucide]

Hello, I've been reading about the similarities between variable refresh rate technologies, and I was wondering if the old AMD proprietary FreeSync over HDMI could be presented as VRR. I've seen some monitors (including mine) and lots of TVs supporting HDMI FreeSync (my MSI calls it "Console Mode", due to it being supported by the XBox Series models).
I don't recall seeing any HDMI 1.x screen with VRR support, I suspect there are close to no controllers available, while there are plenty legacy FreeSync or HDMI 2.x.

It is also interesting that I'm on a NVidia Turing card, which is unique in supporting VRR over HDMI 1.x, so there shouldn't be risk of dumping unsupported bandwidths or something (?). Simply adding a HDMI 2.x block to 'CTA-861' with 'Variable refresh rate' filled up didn't work, the monitor shown no image. I don't expect this to work, otherwise it'be promoted everywhere.. But I would appreciate a more technical answer.

Side note:
My new monitor actually has a DisplayPort socket, but I've discovered the QoL to be so poor on windows.. Extremely aggressive VESA hot-plug detection (not configurable in my case) and malfunctioning DDC/CI (probably an issue of the Windows stack, on Linux works fine).
When my old panel broke I was really looking forward to try out VRR tech, but as a student I use my pc for 90% work and the displayport user experience is really hurting my workflow.
