Hello Guys,
I have the same board (acer-vn7-591g) and would like to use a NVMe SSD. I have already tryed to add the NvmExpressDxe Module to my bios and flashed it back but can not see/use the NVMe SSD, the tutorial I used is this [HowTo] Get full NVMe Support for all Systems with an AMI UEFI BIOS
Here is my clean and modified bios dump: WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free
I hope anyone can help, thanks.
