This is hitting the area I was looking at so I am going to reply here.

I went ahead and enabled the option called something like BLK_V_GED_ALS_SM (turn signal front dimmed as sidemarkers) [don't recall the exact name though and don't have my programming laptop with me right now], but now the turn signals are on full brightness with the parking lights (angel eyes in my case).

Programming can be done with proper OBD-II interface and software.
Is that the option you are looking for?
