To set specific platform you must first GetPlatformTextureSettingsmake changes then set it back with SetPlatformTextureSettings:

var textureImporter = (TextureImporter) AssetImporter.GetAtPath("Assets/SomePathToTextureFile");

var settingsDefault = new TextureImporterPlatformSettings
{
    textureCompression = TextureImporterCompression.Uncompressed, 
    format = TextureImporterFormat.Automatic
};

textureImporter.SetPlatformTextureSettings(settingsDefault);

var androidOverrides = textureImporter.GetPlatformTextureSettings("Android");
androidOverrides.overridden = true;
androidOverrides.format = TextureImporterFormat.ETC2_RGB4;
textureImporter.SetPlatformTextureSettings(androidOverrides);
