Is there any way to get the AMD 6XXX (e.g. 6900) to switch to Manual tuning if it's not already without using Adrenaline UI?

If I have to force reboot (or crash) Adrenaline resets to the default automatic mode. In this mode I can't set clocks/voltages (neither with PM nor OverdriveNTool).

Is there a command line tool to switch to a manual preset somehow?
