Issues add m2 nvme ssd to rock pi4c+

I am trying to add an m.2 nvme ssd to the rock pi4c+.
I have a fully functional os installed on the micro-SD card.
however, when I try to put the nvme ssd in the m2 slot and boot the board the board will not boot from the fully functional os on the micro-SD card.

all I want to do at this point is use the nvme as storage not boot from it.

any suggestions
