Strange. Here is set to dynamic per default.

LOL. Windows users often try to copy their Windows World into Linux :-D

That is already a feature since the beginning
You did not read my website.

No need to import those settings like windows registry keys!
(you can, nothing wrong with that, but..)

What the Registry does in Windows, in Linux is done with so caled
'rc-files'

Start nvdia-setting as root, make the settings to the powermizer and
save your settings in the nvidia-settings tool to the rc-file

/root/.nvidia-settings-rc

and enter (uncomment) the path of that rc file in

/etc/default/switch-x-to

My switch script together with the init/startup jobs installed by the
Janitor script will load the setting you saved there (e.g. Powermizer
status) on next startup.

Maybe you should install a newer driver, at least try it. Meanwhile it
became extremely easy with the Janitor script to change between the
drivers wanted.
If you don't like it, simply switch back to the Driver of the
distribution.
