Yii2. CamelCase in Module name?

Question

Yii

I welcome everyone. There is an ExportImport module. ExportImport module folder. In the url, you only have to write this: exportImport/default/index. Those. I in upper case (as far as I understand, not comme il faut?). If you write exportimport/default/index | export-import/default/index - Not Found (#404). For controllers, this is done - with camelKeys, the word in the url is separated by hyphens export-import/index . But is it possible and how to have it also for Modules?
