Exploring S22+ LDU IMEI repair

Due to some facts in life, I bought an S22+ LDU (SM-S906B), thinking that it just needed to be flashed.
I flashed it but nothing really changed. After sometime I realized that my CSC was WWD when I had flashed an SER firmware. Later I realized that I had to check the repartition option in Odin and extract the PIT file from the CSC file to repartition my EFS partition to be able to access the devices IMEIs. It still didn't work.
Later I changed CSC using SamFw Tool, but my carrier id is still WWD, and I'm still unable to repartition the phone.
I'm not a developer, so I'm not sure that I need to repartition. I already have other data from the EFS partition (MAC addresses). Please, tell me if I'm in the right direction.

Some people say that I can repair IMEI, if I had U1 (I have U3), but there're services that repair U3 phones (I'm too broke for those).
Now I think that I should change my carrier id, I found some video using combination firmware, but currently there're no combination firmwares for U3.
Today I found some comment, saying that to flash CSC you need to have U1, which relates to the claim two lines up, so I feel that I'm on the right direction.
Should I downgrade my bootloader? Is there a way to do it without tripping Knox?
