Done a few already with X17… all smooth.  No need to open ecu.

Option 4: Fgtech Galletto Original

in Boot Mode Tricore

Yes, works well

ecu’s needed when you want to replace your cars engine ecu  with a used  unit.
Your original ECU will have to be ”alive” ( ecu that will still communicate via diagnostics) and the replacement will be compatible (ideally the same part number).

(Fgtech clone won’t do it.)

Option 5: Ktag Original
