Generative expand without use of AI-credits in Photoshop 26 or 27 possible ?

Hello, this is not what I was looking for. It is not about generative fill in  of a selection “in” the picture (e.g. to replace some  removed item). I want generative fill of a transparant canvas area (created by extension of the picture pixels format) after having selected (part of) this blank transparent zone. The only options I see now in PS 26 or 27 is a generative fill with AI ànd Firefly, but this consumes credit(s). So I want to have the old fashioned generative expand feature (could but must not be AI), although without any credit consumption. Hope you or someone else can give me a hint or solution how to operate for this.
