Turn Samsung s20 Ultra eSIM USA version globally

I am looking to turn my current Samsung S20 Ultra eSIM USA version into a globally unlocked device. My network provider is STC and I already have an existing eSIM profile. I am trying to make the phone universal so I can use eSIM , as well as make my phone compatible with more providers.
I searched about this and what did I know is I need to flash the CSC file into global version only..
