After recent update "radeon software 19.12.3" i can't change graphic card on notebook (gaming). Some games need radeon rx 560x, not Radeon Vega 8 Graphics. Help please)
You are thinking wrong. Some BIOS manufacturers do not have this setting either. This setting is only available in the Windows 10 game settings. The internal graphics card cannot be replaced. The external video card can be turned off, but not as a primary.
