May be possible only if your vehicle's EGS HW version can be flashed with the pre-LCI EGS FW.
Please note:
1) Without flashing EGS with pre-LCI FW, you will (likely) not be able to select S-mode. You will need to use E-sys + psdzdata (full) in order to flash the EGS and only if BTLD, CAFD, SWFK and SWFL are available for your EGS HW version.
2) Any time you replace HW that is not supported by/compatible with your vehicle (and included in your vehicle FA), SW recalls (dealers uses ISTA+), ECU ("idrive") OTA and dealer (ISTA+) updates will (likely) no longer be possible without first reverting HW back to factory. You can alway update your vehicle's ECUs SW/FW (for SW recalls and "idrive" updates ) using E-sys but doing so is not for the faint-of-heart. You really have to know what you are doing.
