VRAM issue with Ryzen APU

[lucasmatic]

Fusion 360 reports a graphics issue on my system (HP Envy x360 13-ay0178ng with Ryzen 7 4700U and integrated Radeon graphics). The problem occurs because Fusion misreads the dedicated VRAM. As I get it Windows can allocate more RAM for the APU from the shared memory of 16GB if needed. But Fusion reports only the minimum 512MB that are dedicated from the beginning. The viewport quality is really low because of that.

I cannot change the dedicated memory from UEFI bios because this setting is not supported by HP.

Does anyone see a way around this problem?
