How can I verify that my RTX 3060 Ti VBIOS supports Resizable BAR?

I want to check whether my ASUS ROG Strix RTX 3060 Ti is ready for Resizable BAR before changing anything. What should I verify in the GPU VBIOS, motherboard BIOS, and Windows settings, and how can I confirm that the feature is actually enabled?

You may not need to modify the VBIOS manually. Install the official update from ASUS only if your exact card revision requires it. Afterward, check NVIDIA Control Panel under System Information or use GPU-Z; the Resizable BAR status should show as enabled. Your motherboard firmware and boot configuration have to be set up correctly for it to work.

First, identify the exact ASUS model and check its support page for a VBIOS update that specifically mentions Resizable BAR. Don’t flash a VBIOS from a different model. You’ll also need a motherboard BIOS with ReBAR support, plus Windows configured for UEFI boot on a GPT drive. In the motherboard BIOS, enable Above 4G Decoding and Resizable BAR, and disable CSM if required.
