[HowTo] Get full NVMe Support for all Systems with an AMI UEFI BIOS

@all:
This thread has been designed for users, who want to get full NVMe support for their old PC with an AMI UEFI BIOS by trying to do the related procedure themselves. Since I didn’t spend the time writing and updating detailed guides like the one within the start post of this thread with the intention to do in the end everything myself, I generally do not modify anything upon request.
Users, who just want an already NVMe modded BIOS for their specific mainboard/system and are not able or willing to follow my guide, can search for it within >this< Sub-Forum or send a private request to our BIOS Guru Lost_N_BIOS.

@Lost_N_BIOS :
It is no problem to insert the NVMe and the “SAMSUNG_M2_DXE” module simultaneously.
