have tried it and I think it might just work...
Before doing anything BACKUP YOUR SD CARD ! !
Then find the files Scan/Make/Asia/Acura inside there you will see a car.bmp and a car_new.bmp file.
Rename the car to car_new
Rename the car_new to car
You will have to do this for each vehicle you have software for....

Restart your scanner and see if you have the dealer logos. If it doesn't work. Just reformat and install your backup.
If you update your software, you will probably have to do it again each time you update..

Tell me if it works for you ?

 I did something similar. I got on google and found all of the manufacturer logos I liked and saved them. Then put my SD card in my computer and copied my saved icons into the MAKE directories for each make and it worked fine. When I did the new update in May 2020 my new icons were still there. VIOLA!
