UEFI DXE driver status: Missing GPU BAR0 Configuration (0x01000000000000A2)

[ARX9Mithril]

System

• Motherboard: Maxsun B760ITX D4 WiFi Terminator
• BIOS Version: E2.0D
• GPU: RTX 2080 Ti
• CSM is turned off. Make sure to confirm this in the BIOS and not with GPU-Z or similar since it can be inaccurate
• 4G decoding is enabled. Make sure to confirm this in the BIOS and not with GPU-Z or similar since it can be inaccurate
• UEFIPatch is applied (see Using UEFIPatch for more information). On some motherboards DSDT Patching is also needed
• I have read Common issues (and fixes)

Description

It might caused by flashing VBIOS throughout NVFlash64 without disabling strapsrebar (Cross brand), as the PCI ID changed after flashed the VBIOS, but I cant confirm that. I flashed back to the original VBIOS but it's still like this......
Here is the output from W

NvStrapsReBar, based on:
ReBarState (c) 2023 xCuri0

I reflashed the modded BIOS to the motherboard and I have completely no clue...... Shall I restart from the beginning process?
Best and thanks in advance.
