You can install each AdIX by extracting it's VFX contents to the appropriate directory in Program Files and then applying the Windows Registry changes from the corresponding Registry.dat registry hive files located inside AdIX (import-export it with Registry Editor and edit-replace REG with Notepad to point all keys to correct HKLM\SOFTWARE hive). But to achieve a full scripted installation you'll have to alter each MSI individually to omit it's launch condition (Setup.exe). And you'll also have to write a batch file to remove AdIX files and registry entries (and MSIs as well as they are hidden from Uninstall Programs & Features by default, but still can be uninstalled via Command Prompt using their ProductCode values). I'm not sure if it's still relevant for newer releases, but it worked for Civil 3D 2023 which features AutoCAD 2023.
