Vega 56 Refresh Rate in Mojave

I'm currently running a High Sierra build because of the lack of Web Drivers for Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave (i5-8600K, 16GB, GTX 970), and I'm contemplating getting a Vega 56. I use a 1440p 144Hz monitor and the 970 works flawlessly with it. However, i've run into some YouTube videos that claim Vega only supports up to 30Hz over HDMI in OS X, so I wanted to ask here for verification. Does V56 natively support 144Hz refresh in macOS?
