How to enter console commands without console? (Before starting game?)

[★Captain Kirk★]

There are some console commands that improve performance. But they have to be entered into the console every time ( with console unlocker mod ) Is there a way/file location to enter these commands so that when the game starts they are already in effect?

- Examples -

sg.ShadowQuality 0
r.bloomquality 0
r.mipmaplodbias 1.1

etc etc
