Create DSE without a /conf folder

Trying to build a DSE cluster : ccm create --dse dse68 -v 6.8.3 --dse-username=test --dse-password=test -n 3

Then starting : ccm start

Traceback (most recent call last):

Everything ccm do must be in the .ccm folder.

I wanted to check the conf folder but it's not here:
