GPU-Z fails to read VBIOS from Cezanne, ID 1638 (SoC AMD Ryzen 9 5900HX)
Heavy Metal umlaut Y = $FF = -1 = buffer over/underrun?

GPUCapsViewer reads the BIOS version at least.

The VBIOS for an APU is the BIOS of the motherboard.
 
Does the Save BIOS function produce anything?

I'm not sure if this modern motherboard still has a legacy BIOS, the UEFI has a different version number and date stamp

Only the standard message "BIOS reading not supported..."

I try to find my antique AIO with AMD APU to double-check...

Ye olde AMD Zacate with Wrestler iGPU can be read (but not dumped)
So sth. is different in Ryzen/Cezanne
Maybe other users can jump the bandwagon and test intermediate AMD architectures.
