How do I set certain project properties as variables?

Hello!

I wanna ask is it possible to make "Far Distance" value in Advanced Project properties section to be manipulated by Global value giving player ability to select draw distance based on device capabilities

This is what wanna to control as variable

And in general which of values can be manipulated by event sheet and which don't. If there is way to use JavaScript for that I'm all in for that piece of code too

Here is examples of draw distance

5000

18000

So this is what I want for player to control and some other values too
