How do I change an aircraft with an add-on folder in the community Folder? Community

Hello:
I want to change a couple of the characteristics of Asobo aircraft without changing the .cfg files in the Official Folder. In other words, create a folder to place in the Community folder that, when MSFS2020 loads it will change the parameters I have requested from the community folder.
Much the way that complete mods are done but only for a couple of parameters.
As they say, just the basics.
Thanks in advance.

I am not sure that is possible.
They don’t unlock the cfg files.

Hello:

Maybe I didn’t ask it correctly. The web is full of “mods” people write, their folders go into the community folder, the sim reads those folders and the sim makes changes to the aircraft characteristics. But, instead of changing many characteristics like the “mods” do, I only want to change perhaps a couple.

You can change some of the .cfg files because I’ve changed them - but I don’t like making changes to those files. Thus this request.

The easiest way is to follow the example of an existing mod.
