How do I change Custom URP Settings via Script?????????

Im trying to make a Settings menu for a videogame (kinda obvious if i ask this in this page xd).


SO the thing is, as u see i have this Canvas done and it works quite good.

As u see are different options in my canvas

If I change the preset option VERY HIGH to HIGH, the shadows, alias and so on changes to to lower
resolution options.

But if im in one preset and i wanna change like shadows, the preset automatically changes to CUSTOM

Also i have an URP_Settings for each preset that saves different quality settings as u see down here



So, with that being said, here comes the Problem



As i said if i wanna keep High Quality Preset but also wanna remove Vsync option for exaple, the
actual preset sets to CUSTOM, but it also sets the URP_Custom settings and thats a problem because it has many different options that i cant access to them in-game





Inside the Circled Asset there are many options like MSAA or Shadow Resolution and so on
and there's the problem, becouse imagine, if i have the VERY HIGH preset set and i wanna reduce
the shadow quality to a Half, the preset automatically changes to CUSTOM and INSIDE CUSTOM
i have set that shadow quality is 4096


SO HOW CAN I CHANGE THOSE VALUES AND SET THEM AS THE CANVAS VIA SCRIPT


sry 4 the huge text lol
