I mean that they do them while analyzing CGHS model and similar model. I do not understand the following thing: "why are we satisfied when we obtain the solutions for metrics and fields in conformal gauge for action, which we get after weyl transformation etc?" Because action and equations in, for example, CGHS model has no invariance under weyl transformation and conformal gauge, hasn't it?

It seems to me that you haven't answer my question. I asked about the role and meaning of these transformations in gravity. The connection is not obvious.

Btw, I think you meant $-9 dA\wedge A\wedge A$ instead of $-9 A\wedge A\wedge A$, right? (:
