The scope of who is included under "none" is not provided by the text. For you are anyone to claim this means every lost person is simply altering scripture by addition.
Why not address what it actually means as I have posted numerous times, why avoid discussion of the truth?
Who are the "none" that do not understand, and what is it they do not understand. The Calvinist assumes the none refers to all the lost, but not those regenerated. Does the verse say or suggest that rewrite? Nope.
What do those in view not understand? That by the works of the Law no flesh will
by justified? Yes
Thus the "none" refers to those who believe justification by works.
Why do those in view not seek God. Because they do not seek God by faith!
Psalms 14:1-6 NASB with added clarifications
The fool has said in his heart, “There is no God.”
They are corrupt, they have committed detestable acts;
There is no one who does good.
The LORD has looked down from heaven upon the sons of mankind
To see if there are any who understand,
Who seek God.
They (the fools) have all turned aside, together they are corrupt;
There is no one (among the fools) who does good, not even one.
Do all the workers of injustice not know,
Who devour my people as they eat bread,
And do not call upon the LORD?
There they (those who call upon the Lord) are in great dread,
For God is with a righteous generation.
You would put to shame the plan of the poor,
But the LORD is his (those who call upon the Lord) refuge.
As anyone who takes the time to study the concept, nothing in scripture supports the idea that all the lost are unable to seek God or trust in Christ.
