How to change CSC from XAA to TCE? - Samsung Galaxy S8 Questions and Answers

I bought a S8 + originally from Verizon. Then installed firmware unlocked (SM-G955U1) then the CSC automatically changed to XAA (usa unbranded).
I am currently using it in Mexico with Telcel. Everything works good, samsung pay does work, but I want to active VoLTE and use carrier ID anti spam there's no option to activate that because my CSC is not TCE, the problem is that the firmware is not SM-G955F (exynos version) that includes TCE (telcel México) CSC which allows to go to a specific setting menu to activate volte and ID anti spam.
I'm almost sure it is not possible changing the CSC because proccesor firmware incompatibility Snapdragon (SM-G955U1) and Exynos (SM-G955F).
The question is, can I change the CSC that comes with firmware U to a CSC that is supposed ONLY included in firmware F (exynos) ?
And how to do that?

How to proceed with install branded ROM from my operator in order to get WifiCalling?

Hi Guys,
My telephone operator has run Wifi Calling feature only for branded phones from their own distribution (PLAY telecom from POLAND).
I have my Galaxy S7 EDGE from other distribution and other country.
I've found software from my operator here on UPDATO . COM portal
SM-G935F
Country/Region Poland (Play)
Product Code PRT
OS VersionMarshmallow(Android 6.0.1)
Release Date20.09.2016
PDAG935FXXU1BPH6
CSCG935FPRT1BPH1
PhoneG935FXXU1BPH1
This is exactly what I need and this can be awesome to run Wifi Calling by install branded software (they have other own implementations of WIFI Calling).
The question to you guys: How to proceed with the most clear installation to get software like in branded phones? What I should select in ODIN?
I have to clear all data and install above and change CSC to PRT because my phone has other CRC.
What do you thing? Is it make sense?
This is official software so I shouldn't lost warranty?
Thanks,
Mateusz
Looking for a similar answer for using T-mobile (US) network with the international S7 edge (SM-G935F).
The latest INS (india) firmware for G935F apparently had wifi calling support, any way I can make it work with my carrier in US?
Is that possible to check if below firmware is multi-csc or single csc and which csc are inculded inside?

Flashing G950F CSC to G950FD

I have bought a G950FD dual sim S8 from UAE. In order not to have any limitation from service provider in Turkey (like voLTE, voWIFI or SamsungPay) I am planning to flash G950F CSC. Will there be any complications, what do you think?

Let us all know what happens. I'm curious to see these things on an international level.

Are you sure that your Turkish provider doesn't use the same CSC as the UAE CSC? Most G950F/FD's use the multi-CSC and all you need to do is a factory reset, then put your country's SIM in and it will apply that CSC.
Also, G950F/FD are the exact same firmware/CSC

That is exactly what happened, even better my provider recognized the phone as G950F so there was no need to flash CSC at all.

What means XXX/XXX/XXX CSC codes?

I will try to explain muy question...
Im using a S8 Dual Sim (SM-G950FD) with XSG CSC (In Firmware section appears XSG/XSG/XSG like mi CSC code), but im from Mexico and recently I changed the firmware to another with TCE code, but when my phone starts, after the firmware change with the combination rom, my CSC code was something like this:
