I managed to code the side markers off and separate brake lights from the rear turn signals using FDL coding, but after the previous comments i am afraid to change the typecode, because I do not know what should it be for ece typecode to propetly flash MGU

Can you plese share coding for the rear turn signals just out of curiosity ?

First of all your car is 5R79 according to BMW systems, not 5R89. Once you understand this it's easy to see that you should go for 5R91 since it's based on the same engine (B46D) and x drive configuration. In my opinion 5R71 (B48 engine) will work also fine, since MGU config is not dependand on engine itself. Don't forget that B46 and B48 are siblings in terms of constructions. B46 is ultra low emissions standards for US and B48 is the same engine but just for EU.

Besides that you don't have much options to play around with other the ones mentioned.

I had the same car but without xdrive based on 5R19 and I went for 5R11 and all went fine. One remark though, I've changed FSC region on that car before flashing/coding. I guess if MGU act's same like NBT ID5/6 and you will code it with different typekey the HU will block itself.

Just change TYPCODE does it all. The most important thing is to press "HW-IDs from SVTactual" when calculating the TAL. After the flash, you normally upload the map with the fsc code. A coding change is required for the correct operation of the "Weather etc" application. In addition, of course, KOMBI and RAM unit.
If you are afraid you can flash a converted tal by just adding a swfl file with a given country language and do the encoding, but in my opinion it is more work.
