MSI 890FXA-GD70 Bios on MSI 890FXA-GD65 Board (Enable IOMMU)

I am looking to enable IOMMU on my MSI 890FXA-GD65, however I have read that they only enabled this on the latest bios for MSI 890FXA-GD70.

I know it might not be ok, but since the boards are almost identical, do you think I could flash the 65 with 70 bios?

Some guy here said he did it, but I havent seen anything else.

I spoke to a MSI technical Rep and although this board is fully capable of supporting iommu, they purposely hid this option and reserved for the higher price GD-70.

I'm new to BIOS tech, but is there ways to modify and unlock options in the BIOS before flashing? Would be nice to know if flashing GD-70 works on the GD-65 with no issues.

Reason for IOMMU is so I can do passthrough with ESXI.
