sudo nano /usr/bin/nvmelowpower.sh

#!/bin/sh sudo nvme set-feature /dev/nvme0 -f 2 -v 2

sudo nano /usr/bin/nvmehighpower.sh

#!/bin/sh sudo nvme set-features /dev/nvme0 - 2 -v 0

sudo nano /etc/sudoers

username ALL=(ALL) NOPASSWD: /usr/bin/nvme

sudo chmod a+x /usr/bin/nvmelowpower.sh

sudo chmod a+x /usr/bin/nvmehighpower.sh

open KDE System settings power management menu

Under the "On AC Power" tab under "Run Script" entered the script "/usr/bin/nvmehighpower.sh"

Under the "On Battery" tab under "run Script" enter "/usr/bin/nvmelowpower.sh"

I am probably the one to blame, but in looking at your TL;DR there are a few changes that need to be made:
the nvmehighpower.sh script needs to contain "sudo nvme set-feature /dev/nvme0 -f 2 -v 0" instead of what's there.

The corrected Tl;

Code:
sudo nano /usr/bin/nvmelowpower.sh

Code:
#!/bin/sh 

sudo nvme set-feature /dev/nvme0 -f 2 -v 2

Power State 0 is full power, 1 is less and slower, 2 is even less and slower and on my drive power states 3 and 4 are non-operational. I have used the following as a compromise:

Code:
#!/bin/sh

sudo nvme set-feature /dev/nvme0 -f 2 -v 1

Ctrl + X to exit then enter to save.

Code:
sudo nano /usr/bin/nvmehighpower.sh

Code:
#!/bin/sh 

sudo nvme set-feature /dev/nvme0 -f 2 -v 0

Ctrl + X to exit and Enter to save.

Code:
sudo nano /etc/sudoers

At the bottom of the file add substituting username with your actual username:

Code:
username ALL=(ALL) NOPASSWD: /usr/bin/nvme

Ctrl+X to exit and enter to save.

Code:
sudo chmod a+x /usr/bin/nvmelowpower.sh

Code:
sudo chmod a+x /usr/bin/nvmehighpower.sh

At this point I test each script to make sure they are working correctly. For example, on my system it looks like this:

Code:
[user@pinebookpro ~]$ /usr/bin/nvmehighpower.sh

set-feature:02 (Power Management), value:00000000

[user@pinebookpro ~]$ /usr/bin/nvmelowpower.sh

set-feature:02 (Power Management), value:0x000001

open KDE System settings power management menu

Under the "On AC Power" tab under "Run Script" entered the script "/usr/bin/nvmehighpower.sh"

Under the "On Battery" tab under "run Script" enter "/usr/bin/nvmelowpower.sh"
