MST hub that will uncompress a display port signal into one that doesn't have DSC?

I want to plug an MST hub (one display port input, two outputs) into my one display port output on my thunderbolt 4 dock, and then be able to plug the other ends of the hub into my two 4k60 monitors that don't support display stream compression. Will this work, or is there an MST hub that will do this? Does it require re-encoding the video stream?
