Its not up to InfinityFree what gets added or removed from the servers configuration. If you want to request something to be added, you would be better off asking on the iFastNet Support.
Just like you aren’t owned by your local grocery store, InfinityFree isn’t owned by iFastNet. We are only a customer of them. They build the free hosting infrastructure, so for these system level changes we’re dependent on iFastNet.
