What is the MTK driver installation during the use of SP Flash tool good for?

I still would like to find a way using non-Windows. Because SP Flash tool is using adb as background service - obviously to connect to the phone. But you have to install and configure MTK drivers in the SP Flash tool as well. This part is what I don’t understand what they are good for. I have found no source of information for this. They all simply use it, but nobody knows what it is good for :frowning:
