ViewportScale/Dpi Scale

Hi all,
I need to adjust my custom Dpi Curve in runtime inside a BP.
Problem is, there is no node to set any DpiScale or ViewportScale (just Get, not Set…)
I can adjust my curve in runtime from project setting when I play my game in PIE and this is exaclty what I’m looking for, but from the level BP.
Is there a way to achieve this?
Thanks,
