You can use the free tool LotAtc Configurator to edit/customize profile, easier and simpler than manual way!!!
Profile mechanism
At DCS startup, the %userprofile%/Saved Games/DCS/mods/services/lotatc/profiles/ directory is listed by LotAtc server and will be displayed in the DCS > Options > Special > LotAtc 4 DCS options page
Default profiles are provided with LotAtc server but you can add your own profiles to customize LotAtc as you want. It could be usefull for a specific campaign or mission for example.
Select a profile in DCS Special Page only works for DCS Gui, for dedicated server, check on this page
Go into the %userprofile%/Saved Games/DCS/mods/services/lotatc/profiles/ directory. Just copy custom.lua to a new file for example my_profile.lua.
You can edit any profile with no restriction but files will be overwritten on next LotAtc server update, so copy them is a best choice.
Open the new profile with Notepad++ or any other text editor.
Do not use Notepad, it generally break the lua files, prefer Notepad++
Once done, start DCS, select your profile in the DCS > Options > Special > LotAtc 4 DCS options page
