Need help disabling ReBAR / SAM for ROG Ally X + AOOSTAR XG76XT eGPU

Hi everyone,

I'm currently trying to set up my ROG Ally X with the AOOSTAR XG76XT eGPU (Radeon RX 7600XT), but I'm running into issues and need to disable Resizable BAR (ReBAR) / Smart Access Memory (SAM).

Has anyone successfully disabled ReBAR or SAM on the ROG Ally X? I checked the BIOS, but I couldn't find a direct toggle for it.

Is there a specific BIOS setting, registry tweak, or tool (like AMD Software or CRU) that can force ReBAR off for external GPUs? Any guide or advice from someone running a similar eGPU setup would be greatly appreciated!

Thanks in advance!
