All the data on the home

and all the data on root
is on /dev/nvme0n1p2
.

I want to remove /dev/sda1
from the volume group. I can do this easily, but that procedure involves losing the data stored on the home
LV. I want to keep the data on the drive in case I need to refer to it later. How would I remove /dev/sda1
from the VG without erasing the data?
Thank you!
