How to make my drives separate from each other? Now they behave as one drive?

I am using Fedora28.
My laptop has two drives, and I want to have the opportunity to choose between them.
Now their capacities are simply summed up. As I understand, I can only use them as one drive.
What should I do in order to be able to choose between these drives?
Here is the output of lsblk:

NAME                            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda                               8:0    0 931.5G  0 disk

By default the Fedora installer creates volume groups which behave as a virtual filesystem on top of the physical and logical volumes. I myself appreciate this because I don't particularly care about physical volumes but just want what looks like a giant disk to store my stuff.

There are undoubtedly several ways to achieve your objective, but I have never done it. Backup any data you wish retained because these commands are likely to lose whatever is on the volume.

See vgsplit, pvmove, and vgchange for clues how it might be done.

The volume group facility presumes knowledge of many concepts which are unfamiliar to most users. I found some tutorials which should be helpful:

Why you are saying the two drives are merged in raid0? It is clearly written:

/  and swap

are on nvme ssd, while


is on the sda disk, the hard drive with partition of 1.1TB.

/home is also on sda3.

sda3 and the major part (180 G) of nvme0n1p1 are on the same logical volume (fedora_localhost--live-home).
I want them to be separate.
