Yes, press Esc until it says the mode is 2-A. I'm envious if you can play "uninverted", I've always wondered if it's more natural, but I've never been able to do it. Last week I made 2-A the default out of the box for now, previously it was tank controls. As for using face buttons, I really think that's a bad idea so I don't like to talk about it. You'd have to start by editing the Ex.ini file to remove the custom functions from the face buttons, but currently dashing and activation are fused to the same button, so you wouldn't get very far. I recommend using the practical control scheme. Someday I may make it possible to disable activation with the dash button so it be put out of the way, but I'm more interested in adding a weapon holstering feature so you can use your hand/attack buttons to "activate". I mean it's not worth giving up analog control???
P.S. I'm glad you're asking probing questions, I was hoping from the beginning (now 200d ago) there would be discussion to help to provide supplemental information for those interested. Especially because the control scheme really goes way deeper than anyone would suspect.
