MSI Releases Resizable BAR Support BIOS Updates
MSI, a world-leading motherboard manufacturer, announces support for AMD's new SMART ACCESS MEMORY feature. SMART ACCESS MEMORY is an innovative feature. It allows the system to access the full capacity of the VRAM on the graphics card. Compare to the current solution which has 256 MB access limitation, this feature will provide the users better gaming experience.
For MSI motherboard users, enabling SMART ACCESS MEMORY is quite simple. It only takes a few clicks after updating the BIOS. Go to "Settings > Advanced > PCI Subsystem Settings", enable "Re-size BAR" and "Above 4G memory/Crypto Currency mining", press "F10", to save the settings and reboot. The requirement of this feature is pairing the AMD Radeon RX 6000 series graphics card with AMD Ryzen 5000 series desktop processor. And don't forget to update the graphics card driver to the latest version as well. After these steps, this feature is online and ready to boost the gaming performance.
All the AMD 500 series motherboard from MSI is now ready for this new feature. Users can go to the corresponding support page of the product to download the latest BIOS for this breakthrough technology and enjoy that sweet performance boost.

You're right in that most (all) drivers set it to 256mb and leave it, I'm just stating the option to do otherwise has been there for years. AMD is just finally using the option, with NVIDIA to follow suit shortly.

I flashed this BIOS but I have not tested that option yet.
I have a 3700x and an RTX 2060 Super and I don't know what effect it would have.
It's not going to be a problem, and your system will work just fine. It just won't allow your GPU to use the feature.
RTX 2000 series not supported, here's an article from 'Tech Power Up' (this site):

I updated to get rid of a random restart bug that was caused by the previous BIOS version.
I just posted so people would be aware that that option had been added to this MB's BIOS.
