I'm having a tough time finding a definitive answer, but it seems logical that AMD would enable this. Traditionally, an iGPU would get a designated portion of system memory reserved for it, and unavailable to the CPU (e.g. 512MB to 2GB). But AMD has enabled shared memory between modern Ryzen CPUs and Radeon GPUs, called "Smart Access Memory." So it sure seems logical that they would enable that feature for their APUs.
