Razer Pro 17 HDMI 2.1 to External LG Monitor (32GN650-B)

Hi there, I recently upgraded my Razer Pro 17 (Late 2019) w/ a 2080, to the new Pro 17 w/ the 3080. Previously when at my desk, I connected to a 32" LG Ultra Gear (32GN650-B) via the mini-DP 1.4 to the DP on the monitor. I enjoyed G-Sync Compatibility as well as 10-bit color (setting options in the nVidia Control Panel). Having received my new Pro 17 and connecting it to the same external monitor, I quickly learned that there is no longer a mini-DP out, but instead all video-out is being handled by the HDMI 2.1 port. Logically I would assume the same experience on the external monitor as I did on the previous Pro 17, however, I cannot get neither 10-bit color to appear as a selectable option in the nVidia Control Panel, and neither does the G-Sync setting menu appear in the control panel. I have an HDMI certified HDMI cable, that accommodates the 48 Gbps standard for 4K/8K, so I'm assuming compatibility is not the issue. So I guess my questions are, is G-Sync even supoprted over HDMI 2.1? I thought it was. I am missing something, but I don't know what I don't know. Thanks!
